Fiberglass bonding

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.
