Good Stuff is for the rejuvenation of Durakryl 102 tops.
It is a urethane gel which is intended to be used in refinishing a butcher block. If and modification occurs on a top with Durakryl 102 this is the recommended finish to reseal the tops.
It is also often used when tops are beginning the wear and you want to refinish. Just sand the tops down...follow the directions on the can of Good Stuff and your Butcher Block countertop will be good as new.
