I guess the previous owner had an old bathtub/tiles sprayed with some kind of white enamel paint or something because some of the edges of the tiles that are hit by water constantly are starting to peel/crack off exposing the original ugly tile underneath.
I bought "porc-a-fix" at home depot and was going to give that a try to prevent water from getting into the tiles and peeling it inside out, but is there a more common way to touch-up the tiles treated with such an overcoat? Are there spray-on glossy white enamel paints I should use instead?
Any tips/suggestions much appreciated!
