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!

Worked when nothing else did, easy, with just a scrubbing pad!

Material Type: Powder Ox, Size: 16 oz

I bought a Catalina 1977 sailboat. The hull (freeboard) was extremely oxidized, dull, and had stains and discoloration from the water running off the deck for years; it was streaked. Everything I tried to clean it did little, until a dockmate told me about this. WOW! It WORKED, and it worked very easily. It reminds me of the old "comet" cleanser, that shakes out of a can -- who knows, maybe its the same thing! A little goes a long way, and with very little elbow grease, I was able to attack the discoloration. Great. I also used it to clean my lifelines, which had discolored quite a bit -- and they now look like new. I LOVE this product, but probably won't buy it again for a few more years -- it lasts that long. Can't recommend it enough!
