I did the inside of my tub with the duplicolor stuff, and I have to repaint it after every trip. If ANYTHING is in the bed, it will scrape it up, and you will have to touch it up. The good news is that is comes in the rattle can, so it is easy to touch up. The bad news is, that I have spent more on duplicolor stuff, after all the repainting, that I could have just gone with durabak to begin with. Live and learn.
