I hate my tub
There are three or four layers of paint on the inside of the tub including a layer at the bottom of 2-part epoxy. And there are even more layers on the outside of the tub because that's where they start to rust. I've been using three different paint strippers and a heat gun on my old claw foot tub. They all work... somewhat. But each stripper is very slow and involves a lot of scraping. It's like scratching off paint off with your finger nail.
I've managed to strip sections all the way down to the porcelain and it looks like it's in fair shape. Doesn't look like there's a lot of rust coming through the porcelain. Unfortunately it probably is too porous and if it was painted before with epoxy they probably etched the porcelain. If so it would probably need to be resurfaced. I talked to a guy yesterday who can resurface it with several layers of epoxy and stuff for $245 for the inside, $300 for the outside and $75 to strip it. People tell me it looks beautiful and new when they're done.
I'm already sick of trying to work with this thing so I'll either get someone to fix it or I'll smash it into bit. Apparently that's the way you remove an old tub. You smash it into little bit with a sledgehammer. Sounds like fun but I'm not looking forward to carrying in a new one. Those things are incredibly heavy.
