i hope this is the right section, so
i recently repainted my bike because of rust coming through. so i sanded the spots down and made sure to go over most of it so i wasn't painting above anything glossy. anyways i painted it with rust-oleum primer, then a flat protective enamel and finally a crystal clear enamel (all of them were spray paint) its been a day and it seems like the paint is really fragile (i can push my nail into it)
it seems like im missing something, is there something to harden over the frame?
