My friend recently purchased a house. The previous owner started to paint the porcelain tub, and part of the surrounding tile wall. We're not sure what type of paint she used, it appears to be interior wall paint. Can we remove this? I'll try to find out what type of paint she used, I'm assuming it's a latex. Could we scrape it off carefully? Do you suggest professional help if she then wants to re-do the tub in another color? Thanks a ton......Jody
