This sounds to good to be true, so I assume it is, until I hear
otherwise.

Lowe's carries a product called "Tough as Tile" -- an epoxy for use on
sinks, tubs, etc. It comes in a spray and a brush-on version, and
retails for under 30 bucks.

Given that a professional tub refinish is messy, smelly, toxic, and
runs about $600 - $800 bucks, is this a viable alternative? I have two
horrifically ugly tubs of 1950's - 1960's vintage. One is a seafoam
green but has a nasty ding in it that I can't find touchup paint for,
the other is olive green and has really hard lime deposits that NOTHING
will remove. If it's as simple as painting it over with this stuff,
and it'll work, it might be worth doing it. But I don't want to make
it worse.

Anyone have any thoughts on this product?
