I wish there was too.
I have always thought about if it would be possible to start a listing of various products, with ratings, how they work, what best used for, etc etc, almost like the listings in the back of WhatCar magazine.
It's very easy to go out and spend a lot of money on products, but if prep isn't right, or one bit is missed, you'll be redoing x years more quickly than you need to.
Hopefully a finishing guru will be along soon.
