Fiberglass bonding

I'm just getting started into fiberglass but I already have all these grand ideas set out for me ;-) I really got inspired by Alpines show car (although I WAS interested prior to their demo Civic SI, just not as much). I am curious actually about what fiberglass will and will not bond to. I've had requests from friends to mold their bodykit into their car so it doesn't look as if the body kit was rivited on, feather the edges into the body of the car. Does anyone know how to do this? Is it with fiberglass? If so, does the fiberglass bond to the cars body or do I need to do something special?

Thanks for all your help!

I have done mine, I have found that fiberglass resin and mat, is the strongest, you just have to grind the metal with 24 grit on a grinder, and just run it across the kit real quick. You do not want to fiberglass, or bondo anything that has not been ground down, It Will Pull Away. Then I would use some Duraglass over that, because fiberglass is never very smooth, then use as little bondo as possible over the top of the duraglass and feather it up the grind marks.

Matt, thanks so much! Glad you could help me with that. Anybody know where I can buy dura glass? I searched for it on the internet and can't really find it anywhere. It's almost like it's an unkown thing. I found 2 places on the internet that sell it. Matt, do you have any pics of your car for me to check out?

Thanks,

Well, Duraglass is basically the same as Kitty hair, if you have seen that, They sell Kitty Hair at auto parts stores. Rage Gold is mor like Bondo, it is just supposed to be more light weight and stronger than Bondo. I found both at an Auto paint store, I get Duraglass because it is $35.00 for the Big can as apposed to Kitty hair at $10.00 for the small can. It takes about 5 cans of Kitty hair to equal one big can of Duraglass, you do the math. I can send pictures, I just need your email address.

I learned that the body kit if given the chance will pull away and crack any body filler used to mold it. The answer is to hold the skirts to the car to see about how high they will come on the car, then grind the area very well, with like 24 grit, then mount it as well as you can with rivets (rivets put in every area possible to make the kit wiggle as little as possible) then grind the lip of the kit (just to get it to where it is not smooth and the mat has something to hold on to) then cut mat the size that you want (all depends on how you want the kit to look when finished, whether you still see a lip or if you want it to blend like it is supposed to be there, but remember any place that you are putting fiberglass, or any kind of body filler should be ground down. As a rule of thumb, I always grind like 6 inches past where I am adding the filler) then spread resin on the car area itself, lay the mat, add resin to the mat (make sure you use enough mat to make it strong) Let it dry, grind it as smooth as possible with the 24 grit (without cutting all the way through the fiberglass) then Duraglass (Kitty Hair) making flow how you want, then get a light layer of Bondo on it. Then sand smooth, primer, sand, primer,sand,paint, depending on how well you do may add some more of the primer, sand steps.
