Who knows how to repair cracks in fiberglass?
I have an 85 Vette, and the original fiberglass targa top is severely cracked. My Dad and I think it was either dropped, or maybe it even blew off of the car. Can someone give me step by step instructions for repairing the fiberglass? I would greatly appreciate any help you can give me

it would be SMC not glass and it would be hard for me to give you step by step but you first need to get the wax off it V out the cracks and make up small strips glass mat as you add a strip you want it to be just a bit bigger and wider than the first to put in the V out try finding fiber gell made by swiss that works good try to post heat it and let it cureLast edited by pat mccarthy; 12-27-2006 at 06:38 PM.

I think the last year for fiberglass Vettes was 1975. After that they wee made of SMC (sheet molded compound) With out seeing it I would guess it could be repaired with Panel Adhesive, it's the same stuff as they use when they glue them together.

Would it help if I posted pictures for you guys to see? The cracks are pretty bad, and I started to sand it down today. The previous owner already tried to patch it, but it will probably have to be replaced. Also, how far do I need to sand it down?I have a 1948 Chevrolet Stylemaster and a 1978 Chevrolet Camaro, I had a 1985 Chevrolet Corvette. Im 18.

you want to lay it way out from the crack thickness less than 1/6 of a inch and V feather back. to build it back with mat this is the only way to make it strong mat or cloth makes the part strong on the gell or resin i use and 36 grit on a 3m 8inch soft pad

That should be able to be repaired. Grind the inside with 24grit disc and apply resin and 1 piece of 1.5 oz. mat to the entire inside of the panel, push out the air and let dry grind again and apply second piece to the inside. This will give the panel back its strength and allow you to work on the outside with out the cracking continuing. V out each crack and follow Daves instructions. Make sure you push out the air when appling the mat and resin.
Another question, I was told this engine takes 6 quarts of oil. Is that correct? It's a remanufactured 350 with stock pan.
