when you start off with the fleece wrapped,do you just soak the fleece in resin wait for it to harden then do your layers with matting or do you start off with resin and matting.cuz i tried to just do the resin and it didnt harden very well,i probably didnt ad enough catylyst but i just want to make sure it was a mixing error and not just a mistake in the procedure.

you soak your fleece in resin...I mean alot...keep applying resin untill the fleece becomes "shiny". Then let that cure. Once it is fully cured, start adding resin/matting. The reason your resin didnt cure up well is prolly cuz you didnt use enough harder. Figure about 48 drops of hardener to ever 4oz. resin. Hope that helps.

That is one thing that drives me insane. Counting drops. WTF is that?? is there not like an appropriate ratio?? like 1 ounce to a gallon or something. It would be easier than counting out 20000000000000000000 billion drops. does anyone have a tip on that?

1/4 teaspoon of hardener for 6 tablesoons of resin, I don't remember the measurement I came up with, but put some MEKP and measure how much 12 drops are, as this is how much you add to 1 ounce of resin, OR measure how much the 48 drops are per 4 ounces

or insteaaad of using fleece use a considerably thinner material like grill cloth, panty hose or any other polyester fabric, that doesnt rrequire a gallon of resin for the first coat..

I remember reading on a post here about thinning out the resin with acetone before you apply it to the cloth, do you guys know anything about this? Thanks.

it helps the wetting....

the point of the matter is though that the strecthed material has next to no strength what-so-ever...so why not use something thinner, that doesnt require a gallon of resin in the first place....all you need is something that will get hard enough for you to apply mat too..

I've got some pretty thin fabric that is real stretchy that i picked up today do you think it's worth thinning out the resin, it shouldn't have any trouble wetting out

Hey CrazyOldCougar, how did Grantd get his first yellow star with just 56 posts?  Not Fair! 

Well, dont tell anyone, but Tuesday, I used pantyhose to mold an additional gauge pod into a dash.  I added a single layer of thinned resin as the Guru concurred and BAM!  It was done.  Yeah, listen up learners, there are not many reasons of logic to use a thick fleece material for every fabrication you construct.  Especially when a piece that you are fabricating does not support a substantial amount of weight or if its not going to contain a positive or negative air pressure, such as the gauge pod I mentioned.  All you need is something to exhibit a hardened general shape that will provide a foundation for your additional finishing touches.  However, when using thicker fleece you do not always have to soak it initially.  What you can do, of coarse depending on nature of build, you can wet one side, let fully cure, and then coat the other side maybe a little heavier.  This way you dont have to race your resin's gelling time.

ok well it sounds like thinning is in fact a good idea, what kind of ratio's do you guys use with the acetone?

I tend to use grill cloth, instead of fleece, when doing the smaller stuff. It stretches really well and is alot thinner. It also takes a good soaking with resin and is ideal for tweeter builds etc.

In a car audio mag i have they started the first layer of a center consol sub box in a honda element with sub box carpet and then added a couple layers of FG. They said that it would be pretty strong and soak up a lot of resin though.

Anyone here ever tried using carpet for the initial layer?

I would have prefered not admitting this, but yes aznboi3644, I did back in the day soak some automotive carpeting from J.C. Whitney.  The area was large and.............WHEW, what a waste of resin!!!!!!.  That sucker must have soaked up 3 gallons of resin before it got scrapped.  LOL, what a flashback.  We (friends and I of the late 1980's when minitrucking was making the grade) thought we were hot stuff creating things that didnt exist.  None of us had near the income we do now, so we often look back and laugh, but dont dare tell.....until you had to ask that question.  We were visiting the B. Dalton bookstores and Hastings, to name a few so that we could take a look and remember what George Barris, Ed Roth (older customizers) were up to.  The books didnt show everything, appearantly they were creating these books to show off instead of instructing and behind the screens of what they were really fabricating with.  We saw "CHICKEN WIRE" in a background!  So, even now I use 3/8" or 1/2" wire mesh for some body moldings as well as plugs.

.....uh,

So its not that good of an idea to use carpet like in my magazine?

pajokijr, check one of these MEK DISPENSER from Select Products to help you mix the Resin and the Harderner better. posted_image

Quick question sorry (im pretty new to fiberglassing)

So is fleece strong after being resinned?

Everyone here is saying to fleece then add a few layers of glass.

On "Unique Whips" (Yes i know Reme has no logic behind his boxes, he just makes them to fit) Reme only resins a layer of fleece then calls it a day and bondos then paints.

Could i just ad a layer or two more a fleece if i didn't feel like buying glass?

Thick fleece is strong if soaked completely, but not strong enough.  That is the reason everyone that chooses integrity over cheap bling will add a number of layers of FG mat material on top of this, and then smooth it with body filler, then prep for finishing.

I will never, ever use carpet of any kind again to add resin to for fabrication.

Unique Whips is TV.  For one, its a guarantee you didnt see everything.  Two, he may have used more layers under the body filler, you only saw the time elapsed build.  He (Reme) probably whips this stuff together just for quick looks to make the show.  All of a sudden I dont have anything good to say about TV fabricators...  other than, I wish I had the free time to have a clean shop like thiers, my shop exhibits proof that some serious work is being performed on a daily basis.

reme doesnt just use one thing of fleece,he does add matting to all of his boxes they just dont have the time to show it all.i know i thought the same thing until i went down there and talked to him.i was just as  confused.but the fleece hardenes a little bit to give you a base to lay the matting on. from what i understand.

Ah, ok, I get ya.  Yes, thats the objective is to have the fleece serve as a shapeable foundation in any shape anyone may desire.  FG mat or FG cloth weave serves as the stronghold for the complete fabrication......beer time, talk to everyone later.
