Can I use paint removal on fibreglass I have a old one piece front end for my 1956 Chevy it has old paint when you try to sand it off it plug up the sand paper
No it's not a good idea. Any areas that may have exposed glass starnds can wick it up and then it can seep back out later ruining whatever work you have done on top of it.
Another opinion....yes you can. I have stripped my Corvette twice with paint remover with absolutely no problems with it. I used what was called aircraft paint remover.
Ok this paint I can scrap it off in. Some spots but some other spots it's hard and just gum up the paper I will try a small spot Thanks
They used to make something called "lacquer stripper" for stripping corvettes. Keep in mind that most paint remover will soften and eat up fiberglass polyester resin if it is left on too long
I stripped my Corvette with some stuff that is no longer available, worked good but was messy and time consuming. I had removable parts, the hood, trunk, etc. media blasted...it is worth it.
I'm all for using vintage stuff as much as is reasonable. Reasonable is will you ruin the vintage look you are going for and/or is it saveable for a reasonable cost VS a new front clip? A 50 year old 'glass clip that was left outside in the sun and has damage will often be a ton of work and not a good finished part. Explore all options!
