>>1976285I use some kind of chemical paint stripper, or a sand blaster to remove the paint for big projects. If the paint isn't chipping you can get by with just scuffing the existing paint with some sandpaper, cleaning it well with some kind of solvent, like mineral spirits, then hit primer. multiple coats with time enough in between for it to dry, so you don't get any runs. you want the primer coat a bit heavy, but you'll need to build it up through multiple coats. Let it dry for a day or two, then hit that with some fine sandpaper, clean again with a little mineral spirits on a lint free cloth. If your primer coat is nice and smooth then you can usually just spray on some white protective enamel and have it look great, without any further sanding or a clear coat.
Anyway there's a lot of rattle can paint job info out there, but you can get good results with minimal effort as long as you're patient with your sanding and prep work, and patient with spraying thin, light coats and letting it dry.
If it looks ugly just spray another color into a bowl, dip a finger or brush in it and flick it at the forks and and the splatter effect will hide imperfections
