Got the boat ready to go this past weekend. Pulled her out of storage and started scrubbing. Wifey brought out a Magic Eraser (must have when you have a 2 year old in the house). GOOD GOD! It's incredible. Every scuff came right out. You know the little ones that get left when the cover rubs. Or when you drop your bimini pole on the gell coat. Got rid of the scuffs in the interior vinyl as well. Am I the only that's used one of these to clean their boat. I've never read about anyone else on here using one. Two thumbs WAY up!
