I have read all over that you shouldn't use BF or Z (with zfx) more than 3 times in one day. I know there is a 1 per day rule with klasse.. but that's because you need to give it time to cure. It seems that even taking the time to let the Z/BF dry and cure a little you could easily do 5 coats in one day. What makes 3 such a magic number? Is it only a sugestion to do only 3? Or is there some logic and chemestry behind it that makes more than 3 detrimental to the finish?
