I've heard of some sort of paint stripper which is applied as a gel and left to soak into the paint and - allegedly - remove quite thick layers in one go. Anyone used any? Does it do what it says on the tin? Good types?
I have an Edwardian cast-iron fire surround to strip. I don't think the paint is particularly thick, but there's a flower pattern in the metal would will make scraping the paint off very fiddly.
