This stuff is amazing. My canoe has never looked better. I applied 2 coats to start then a coat a day or so after we take it out of the water. The beading action is great too. The canoe is dry minutes after removal from the lake.

This is a great product for maintaining the finish on your kayak and for restoring old boats. It's very effective on hatch covers to restore dull, scratched plastic or rubber. Hatch cover impossible to get back on? Spray 303 on the inside edge of the cover and also the rim of the hatch opening and you'll be amazed at how easy it is to get the cover on. But be careful: it's possible to use too much 303 so the cover comes off too easily.
Also use it on the cockpit coaming.

Be careful when loading your kayak after polishing it because the 303 will make it quite slippery to handle. I don't use it on the hull for that reason, only on the deck.

We all need to do maintenance on our canoes or kayaks. If you have plastic or gel coat, get yourself some 3M 303 Aerospace Protectant. It's not the cheapest stuff, but it is the best I've seen. It was designed for protecting finishes and plastics for commercial airliners and the US Air Force uses it.

It is a UV protectant that doesn't leach out the plasticizers. Since it contains no silicones and is water based, not petroleum or alcohol based, it's a safer for the environment. But most of all, it works. It will protect your Royalex hull or the gel coat on your fiberglass or Kevlar hull.

Spray/Wipe it on and you can even just leave it to dry, though I use a sponge. It will protect your investment better than any other product I know of. BMW no longer recommends Armor All because it can leach the plasticizers. 303 won't. It can be a bit difficult to find, so try a local Marine store or order on line.

The sun deteriorates polyethylene. This spray is expensive, but provides UPF 40 to protect your kayak. Also restores faded color.
