Fiberglass hood repair/correction question

Fiberglass tends to have a memory, the next time it gets hot, or up to temperature, it will probably return to where it was originally. Forget about the gel coat, in the end, gel coat is your enemy. It has no strength, it's just there to fill, so that the Fiberglass will lay without gaps. They usually use polyester ( cheap resin) for their lay ups. Unfortunately, I know enough about fiberglass to be dangerous. There are more ways than one to accomplish your issues, and, they may or may not work. I don't believe that I can explain here how to do it, maybe someone else can. Sorry.
