hi, i stripped my truck with aircraft paint remover. it’s an old 1970 ford. i would like to epoxy primer it next but not sure what grit sandpaper to use. i heard 80 grit but some say no. i know this is not the best method, i mean with sandblasting and sodablasting being probably a better choice but i’m on a limited budget and i’ve already started it. could you tell me what grit would work for the epoxy to hold. thank you
