Harmony 303 UV Protectant is a must have for any kayak or canoe enthusiast. More than just a water sport UV protectant, Harmony 303 is an “Aerospace” protectant that helps rubber, vinyl, plastic, leather, and fiberglass stand up to the rigors of damaging UV rays. Harmony 303 UV Protectant is water based, so it’s easy to apply and is environmentally friendly.

Overall Review

I would rate my review of the Harmony 303 UV Protectant as 5 out of 5. This stuff really protects your gear and equipment! 303 Protectant is very simple to apply; just spray it on and polish it away. Harmony 303 UV Protectant even restores faded plastic, vinyl, and fiberglass back to their original finish. Harmony 303 UV Protectant is suited for many applications including canoe and kayak hulls, car tires, dashboards, waterproof dry bags, PFDs or lifejackets, pool toys and more!

    I have used 303 on my kayak since new, bought in 2005. My kayak still looks new. I apply it at least twice a year. I bought a used kayak last year that had never been garaged…been sitting in the open for several years. After a good scrub and drying off, I applied 303 and it brought back the color and gloss on this faded beauty. It also works great on dashboards, tires etc. Well worth it of you want to preserve your gear.
