I'm repainting a Kia daily driver and have gotten to the plastic parts. I cut a sliver off and it floats in water, so I'm planning to spray adpro over the bare plastic parts and then epoxy primer over that. My question is, if the paint underneath is in good condition, will spraying adpro over the paint, cause problems? If it does cause problems, how soon would they appear? I have attached a couple pictures of the current state of the paint and it feathers out pretty well when sanded. Thanks for any feedback you can give.
