i finished bondoing the fiberglass baffle on my enclosure, and did some layers of primer. I got really impatient, and did multiple layers without letting each one dry first. after i "thought" the layers were dry, i proceeded to sand, and ended just ruining the primer. its really bad now. a week later, you can still put your fingernail in the primer and it'll show. i attempted to scrape the primer off, but that will take forever to do the entire box. my dad is friends with a guy who owns a body shop, and he said he'd get the box painted the exact color of the car for free, but i want to remove all the primer and give him a good surface to work with. how do i get all the primer off? scraping with acetone jsut isnt cutting it. could i just body fill over the primer?
