Re: Do the spray on shower surround refinish paints work?
If you don't care what it looks like, then do whatever you want. If you want it to look nice, professional, and last more than a week or two, then replacing with a good quality surround is the way to go.
It has been many MANY years since I've purchased or installed one of those plastic surround kits, very cheap, and looked it when done. They are glued to the wall with construction adhesive or similar, so there will be fairly significant wall damage when removed, this damage should be repaired before a new surround is installed.
Personally, I would opt for a tile surround and seal both the tile and grout to prevent staining, at least minimize it. Another step, after it's sealed really well, is to apply a few coats of Rain-X. Rain-X is a polymer film that prevents things like water and mineral stains from sticking. DO NOT use it on the floor, as it is slippery, but for walls and glass it works great.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
