Works much better than the original applicator which left streaks and overlaps
Works much better than the original applicator which left streaks and overlaps. Much easier to use on contours and crevices.

Game Changer!
So much better than the applicators. Easier to get nice even application on RVs. Does much better getting around the awning poles and different covers.

Absolutely a miracle substance!
Material Type: Powder Ox, Size: 16 oz
I have a couple of kayaks made of various resin types, and all were showing severe signs of oxidation on their paint jobs. The newest is probably 20 years old, so you can imagine the oxidation. All I can say is, I was greatly surprised and pleased with the result. Other than the scratches, the oxidation was almost entirely removed! I'm a true believer in this stuff!
