I need a recommendation for a product. I have a fiberglass hood on my 2002 Gt. There is a metal striker plate for where the hood latch contacts and connects to which is bonded into the fiberglass. Well that fiberglass after repeated slamming over the years is cracking all the way around that metal plate. What product do you think i should use that would be a very tough material that can fill those cracks and make it structurally strong again? I was looking at my package of JB weld and it says its a cold weld with metal in it. It says it bonds to fiberglass, think that would be a good choice?
