Ok, but you're not factoring in the time and money for doing the alternative.

How much is that gal of acid thing? About $30, right? Well, when you factor in the install/uninstall labor stuff or your time.....is that close to that $90 mark?

I'm not trying to argue at all, just wondering really. If you're gonna do it all yourself, then it will be less expensive the other way. If you're paying to do it, I'm not so sure.

Good luck either way.
