I just finished mine, love it. Used about 1/2 gallon for most of the tub, there were a few areas I didn't want herc'd.
One tip, make sure to do it all in one day so your rollers dont try out like mine did.

When I did mine I took the whole interior out, including the rollbar. Only tip I have is to spend a bit on cheap bolts and plug the bolt holes so they don't fill up. When you are done you just unscrew them and the threads aren't messed up.
