I used some furniture remover stuff on the inside of my hardtop to remove the glue that was left over from the PO putting indoor/outdoor carpet on it. I used a razor blade to remove it and surprizingly not much paint came off. So using a plastic scraper, I think it would work. Like others mentioned, try a small spot first. Seems like it was kinda time sensitive; the longer it sat the more paint it removed. Being house paint, that furniture remover usually bubbles that paint really quick. Good luck.
