Subject: need to bond something to bumper
Date Posted: April 25, 2005 at 10:53 PM

I'm working on a custom front bumper for a Camaro Z-28....i have the pieces cut out that i want and fleece is hot gued on (from behind so i dont have to get resin on the glue) and before i continue i need to ask a few things.

Will fiberglass and/or kitty hair bond to the rubber/plastic material?  Its more of a rubber cause when i was cutting it, it would cobweb and i could gather up the 'cobwebs' and make a rubber ball.  would i be fine with this or should i just test out a little bit.

oh yea...another question.  i need to fix the hood on it...it has a few chips (some are pretty big) out of the front of the hood.  i ground down the area and grooved it both ways.  will a long strand kitty hair be fine to extend these areas of the hood without breaking off when the hood is closed or someone acidentally hits it?

you may have more luck with the hood then the bumper, does this thing have a fiber hood anyways? camerslows usually have fiberglass everything right? the bumper is probably a polyurithane or something like that (i don't know exactly what they call it) i don't think fiberglassing onto this is going to be very favorable, you might have to glass the whole thing a LOT so that it's firm and doesn't bend, cause if you have a bit of fiberglass on the corners or something, if you bump something, those peices are going to crack and fall off, you might have to make a mold of the bumper and just make your own all out of FG,

allright thanks.  yea this camaro has a FG hood, although some do come with steel hoods. I'll try to bond a bid to the bumper and if that doesnt work i'll make a mold...i was hoping i didnt have to go this route as i might as well have started from scratch...oh well, I'll see how it goes.  I'll take a few pics too.

that's good, i'd like to see them, you might just have to glass it all, maybe not make a mold, but do like 5 or so layers, then put some screws (or something that will get into that plastic) then do a few more layers, that way the fg can actually suport it'self and it wont let the bumper move enough to crack the fg, i had to do this with plastics inside my car for the dash (they were to flimsy so if i just bondo'd part of it they would have moved on instalation and cracked it all off) fg sticks to plastic a little, but bondo will pop right off if it moves around

umm actualy you might want to do a little research first because your hod is probably SMC not fiberglass.

most people mistake the 2 but fsmc will have a smooth finish on the unseen back sides, where as fiberglass will show the pattern of the fibers.

OK...thanks guys, I appreciate the help.  I tested out the FG and kitty hair on the bumper and neither sticks, although it sticks better to the paint so i may just rough up the paint a bit rather than removing it totally.  Good idea about the screws, I'm going to pick up a gallon of resin and some mat today so i can cover the bumper, then I'll rivit it all in place.  I was thinking like 2 layers of FG and then rivit and then another layer or 2 of FG followed by some kitty hair and Rage...hows that sound?  or should i skip the kitty hair and just do another layer of FG? 

The hood looks like its SMC then as it is smooth on the back.  Either way it should still be fine to FG on right?

I got some pics taken, but didnt get around to getting em on the comp. so I'll be sure to get em up tonight.

grrr...didnt upload the pics yet...too busy getting the motor together.  But i did get a chance to chip away at the FG and kitty hair, and waiting the extra day made a biggere difference than i thought.  I was able to chip the FG away from the exposed part of the bumper with a screwdriver, but where the FG was on the paint i was only scratching the FG...so I think It'll stick pretty decent now, and the parts that I fleeced and glassed yesterday are just as flexible as the rest of the bumper, so i think i might just do 2 layers mat and rivit it and then 1 layer mat, and then finish it up as It doesnt seem like it needs the extra strength and support now (the glass want cured on the inside yesterday...hey, I'm still a newb at this.)

i think i might do a little more then 4 layers, maybe like 6 or 7,,, just incase someone leans on it or taps it with a car, so hopefully it wont crack as easy

I put 2 layers of mat on with a mixture of resin and short strand kitty hair which worked out quite nice and is really thick.  I blended the whole front piece together (except for the body kit pieces at the bottom cause they connect to the fender, past the bumper and wouldnt work out that great unless i fused the bumper to the car.)  I'm going to abuse the bumper tomorrow to see if it bonded nicely, and if i have any problems at all i will rivit and add more.  I'll let u know how it goes.

Basically the plan is to put a grill (probly billet) in the area that is open..although i still have to add a piece of FG to raise it up (minor) and then where the origional oval turn lights were i'm going to add round ones near the edge to give it a wider stance ( I'm toying with the possibility of adding 2 bulbs per light, one would be white light which will be connected to a switch and the other will be an orange light for the turn signal.  I'm just wondering if u wont see the turn light when the white light is on.)

And the hood scoop is actually for a 2000 cavalier.

looks good, that's a different style then i've seen on a camerslow, but it looks kinda cool.. umm i think the billit idea is pretty good to, i think it would look way too euro if you did a mesh or something, are you going to have it custome made? or do you think something will fit in there, that jdm or whatever bilit company suposedly cuts to fit.. (they are all over truckin mags and stuff like that) as far as the lights,, if you want the yellow to show good you can hook up a relay to runn off the yellow lights (not power them, just kinda get a signal off of them to turn on or off,, if you power the turns with them they might make it blink crazy fast) but use a relay to shut off the white light when the yellow light goes bright for the turn

thanks Captanham.  Ive never bought relays before...u think the guys at Radioshack will have em?  just a basic relay? 

Since the billet wont be chromed or polished (nothing else on the car is chrome) I will be painting it (not sure what color yet)  so i will be making the billet grill myself.  It wont be an amazing grill or anything but it should look pretty cool.  The camaro really isnt a money maker project as i get to do a bit of experimenting on it...but the owner is paying for materials and I'm doing it on my spare time.

yea that's cool, if you are going to paint it you could use cheaper things than billit to do it,, but whatever you got works for you i guess....

the relays you can get anywere, walmart sells them, radio shack, auto zone, any were, just get a normal bosch style relay, or automotive style relay (same thing) then you can use this basically just to cut power to the white one only when the yellow one gets power, i think that would look pretty cool, if the lights are close to each other, then at night it would just look like the light changes colors from white to yellow, if you get a hyper white (the blueish kind) this effect would be more ovious, i think that would look pretty hip

thanks again for your advice.  I looked around the shop and i think i can whip up a grill out of some foam and thin wood strips and some fiberglass...definately cheaper than billit.

I was planning on using a piece of PCV pipe and a cap at the end (spray the inside with chrome paint or something and then putting the lights beside each other.  The glass cover on the front would be from a small halogen light or something.  I cant seem to think of another way to do the lights, so hopefully it works out.

that's cool, i dunno about the pvc, that'd be a really plane look, it might look good tho, you never know, the grand prix's (new ones) have something like that, with a divider in the middle and they have a fog light on the bottom and a yellow turn on the top, they make the yellow turn very bright by using a dual filimint bulb and powering both of them up for the signal, this may work for you, also you can check out ebay for some cheap euro clears for some import or something, pay 20 bucks for some old honda corners and mold those in, it might look cool,, heres some stuff like what i mean

https://cgi.ebay.com/ebaymotors/dll?ViewItem&rd=1&item=7970264664&category=33717

the top two would be the easiest, cause the lens comes apart easily from the back, so you could glass the back into the bumper and then just screw the lens on, the other ones you would have to fab up a way to hold the lights in there, just an idea... have fun

the 93-02 lights look pretty sweet.  I'll check around the wreckers and see if i can find something that would look good.  I was thinking round because i dont think square would look good and oval was what it origionally had.  I'll try a few different shapes in a photoshop program and see what looks best.  Thanks for the help.

I suck at photoshop, so i dont have anything to show right now.  My dad bought some garden lights and we're only using some of them so I grabbed 2 spot lights.  To house the lights i got some small PCV parts (plug'n'clean?) which is 2 parts.  one part is a short female threaded tube and the other is a male threaded cap with a square on the end.  2 lights fit perfect side by side in the little square.  I'm going to cut a hole in the back of the spt lights so i can fuse the PCV with the Spotlight.  The spotlights have a nice chrome inside with a Halogen style lense. 

The lights will be positioned pretty much where the old lights were, but lined up with the outer head light.  I was thinking of putting 2 more lights in the grill...but a bit bigger, kinda like the new mustangs.  what do u think?

the lights are the smaller dash style lights, but u can buy LED bulbs and different color bulbs for it, so it could get pretty funky.  And i got the relays today too...8 bucks a piece from a local automotive store cause walmart doesnt have em here.

8 bucks? WOW, they are like 1.50 here

Hmmm...I think i'll have to look around and see if another place sells em for cheaper.  I got the lights setup and installed in the bumper.  I'm not totally sure how to wire the relay though...the parts guy showed me the Power in and power out terminals...are those the ones i hook my white lights to, and then hook up the turn signal lights to the other 2?  I could probly figgure it out in a couple tries but i'm not sure if i have to hook up a ground to it or if i just have the power wires running to and from it...I'm guessing just the power wire though.

I'll be making a new thread later with a bunch of pics...I'l probly have it ready for paint in a couple days since i work on it after my job.

see if this makes any sense to you, the dark parts are the relay (i know it doesn't really look like that, but that's the wiring schematic for what's inside of one of those)

Well i hooked up the relay.  when i connect a 12V source to the 87a nothing happens but if i connect the 12V source to 85 the turn signal light turns on and the relay clicks...and if i touch the 30 the white light turns on.  Isnt the white light supposed to be on when i have a 12V source to the 87? and then turn off while the signal light turns on?  I appreciate the help.

are there 4 wires like in my diagram, you have a - and + for a steady light and a blinking light?

I have it like in the diagram...the 12V source for the white light is connected to the 87a terminal and the + wire of the light is connected to the 30 terminal.  do i have to connect the power source to the + wire?

this is what i did and what it looks like to me in the diagram.

+ wire of marker is connected to the 30 terminal...the - is grounded to the chassis.   the + turn signal wire is connected to the origional + wire and both are connected to the 85 terminal.  the - of the turn signal is connected to the origional - wire and both are connected to the 86 terminal.   The 12V source for the marker is connected to the 87 terminal.

i didnt have the keys on me so i didnt get to test if the turn lights worked properly or not, but i figgured if i have the marker grounded to the chasis and the + wire directly from the battery to the 87 terminal that the marker would turn on.  If i connect the 12V wire from the battery to the + wire on the marker it does turn on, so its grounded properly.

do you have it on 87 or 87a? try switching that terminal, try the turn signal, if they both come on when the turn goes on then that's all you need to switch, this still might make it blink fast, i'm not sure exactly how it's set up

it only has an 87, not an 87 AND an 87a.  They both turn on at the same time...I tried a combo of different ways and ended up frying a relay (it was kinda neat cause it made a really high buzz noise and then quit)  Do u mean to switch the 87 with the 30?  for now i took out the relay and just hooked it up with the constant white light and the signal light, but i need to change the bulbs cause the white light is too bright for the orange turn light..so i might get blue for the main light and a yellow LED for the turn light.

you need a relay with an 87 and an 87a, the other ones wont work

yea, like 99 % of all relays have the 87 and 87a, but some don't, i got ****ed with that once, i sent someone to an autozone to get a relay for me and they got one that didn't have the 87a, haha, ohh well, anyways, yea, if you can't find any you can get them off the net easy, you will need one for each side (i assume you know that already, but i'm just sayin it anyways)

Wahoo.  a buck cheaper (not sure if the guy gave me a better deal cause i usually deal with him).  I managed to get the proper relays this time.  It looks freakin sweet.  I'm tempted to do this on my own vehicle too, I love it, lol.  Thanks a bunch...I'm gonna see if I can get my bud to use his digital camera to take a short movie and then post a link (if i figgure out how)  My buds dad found some cool metal that we're gonna use for the grill.  Its pretty much solid metal with lots of tiny holes (u can see through it but not that well.) it looks pretty neat (one of a kind) I'm waiting to post the pics till i get to the primer stage which should be a couple days since i got the Rage almost smoothed out (few little spots to fill)

for some reason my buds computer doesnt recognize the camera, so i gotta wait till the software gets reinstalled or something (his dad works on computers, so whenever he gets around to it)  But the grill is almost done (completely different idea than i started with, lol...I changed my mind 3 times for the grill, but its pretty cool)
