I can only speak about what my sibling went though. She use to live in a 1 bedroom in Pacific Heights… I recall the bathtub was cracking and pealing, and one of a company was hired to resurface the tub and coat it. It looked great for the first two years, but about after the third, it started flaking/pealing from where the drain fixture was… I don’t know if this was just a bad job from the person that did it, or if they just don’t last as long.just seemed to be at places of joints/etc, it would be difficult to prevent things from separating…
