I would like to change the color of my bathtub. I now have a old blue tub, that is in very good condition, with no pits, but I have recently changed the colors in my bathroom and would like to change the tub and possibly the commode to off white or beige. Is this possible? Will it peel? Please let me know if there is a solution, as we are not in a position to replace at this time. Thank you for your assistance in this matter.
