Get some gel coat to finish it and if done properly is should shine.

Nate as long as it's not around the hinge area I use polyester resin mix and cut up some small peices of mat to help fill and stabilze the the resin if you can back up the areas that are cracked thru is the easiest, then do a repair on the outside. You don't need the strenght of epoxy and poly won't hold well over it, Gel coat is a pain in the butt and never comes out he right color--Bob

Re: Fiberglass Body Work

Well, I never had the time to devote to a good answer before, I do now, so here goes.<br /><br />I cut my teeth in the bodywork field on Covettes in about 1970. The Poly will be fine. Here are the basics.<br /><br />Remember, if it shows a crack, it "IS" all the way through.<br /><br />Grind it out all the way.<br /><br />The glass on a truck is usually about 1/4-5/16 " thick when you have it groved out enough you will have beveled it out to about an inch and a half on both sides. More is better and stronger. <br /><br />Allways better to patch front and back. Fill on one side and just a one layer backing on the other.<br /><br />The rougher the better, 40 grit grinding disk required.<br /><br />After the repair is made, bondo and regular automitive painting practices are fine.<br /><br />Place a box fan next to where you are grinding, pointed right at the area you are working on, it will greatly reduce the amount of glass you will get on you. Suit up with a painters suit and tape around your wrist and neck. Were goggles, and use at least a dust mask. When you shower, use the coldest water you can stand, it will make you poors close up and you wont wash the particals into your skin deeper.<br /><br />Hope this helps some, glad its you and not me. :eek: :eek:
