I have a little senario. I picked up a fiberglass 32 Vicky body. Yes I know fiberglass lol. Cant afford the real deal so this will have to do. Anyways here's the trouble I have. The previous owner of the body hacked out the center of the roof to put a roof insert in like a real 32 and made a mess. He also threw the price away he cut out. So here's where I am at. What's a good roof filler out there for one of there that I can pull a mould off of to make a glass insert for it. I don't wanna put a steel filler in because of the different expansion rated and cracking and such. Thanks for any help!
