303 Marine Aerospace Protectant for Boat Vinyl, 32 oz | Provides UV protection for marine vinyl and surfaces while helping prevent fading, cracking, and staining.

I’ve been using the 303 Marine Aerospace Protectant (10 oz spray) on my kayak and a few other outdoor plastics, and it works exactly as expected. It’s very easy to apply—just spray on and wipe down—and it spreads evenly without leaving a greasy or sticky residue. The finish comes out clean and natural-looking rather than overly shiny, which I prefer. The main benefit is UV protection. It noticeably helps prevent fading and drying on exposed plastic and vinyl surfaces, which is exactly what you want for anything that sits in the sun a lot, like a kayak. A little goes a long way, so even the 10 oz bottle lasts quite a while. For regular outdoor gear maintenance, it’s simple, effective, and worth having around if you want to keep plastics and trim in better condition over time.

Excellent product covers and protects as promised

I bought this for an outdoor vinyl cover at my wife's suggestion, and we could not be happier. The product does everything it advertised. We washed the cover with soap and water. Allowed the cover to dry and applied a coat of the protectant. Renewed the look of the cover instantly. A couple days later added a second application and the Vinyl seemed to regain some of the elasticity it had when new. Costs more than some other protectants but worth the extra, in my opinion.

This product refreshed the door seals on my 2018 Sierra. No more wind noise!

I bought this protectant to help preserve and restore outdoor surfaces, and I’m impressed with the results. It applies easily, dries to a smooth matte finish, and doesn’t leave behind the greasy or overly shiny look that some protectants do. I like that it helps repel dust, dirt, and staining while adding UV protection to help prevent fading and weather damage. The finish makes surfaces look refreshed and closer to their original appearance. The 10 oz bottle is a convenient size and a little product goes a long way when applied properly. This is a great option for anyone looking to protect marine, automotive, or outdoor surfaces and keep them looking newer longer.

Awesome material. Use on any vinyl.

“Pontoon Seat Savior – This Stuff Works!” I’ve tried a lot of products over the years to keep my boat looking sharp, and nothing has impressed me like the 303 Marine UV Protectant. My pontoon seats were filthy — black scuffs from the cover, dull vinyl, and spots I thought were permanent. One spray and wipe later, I was shocked. The seats looked brand new, like they just came off the showroom floor. ✨ What I love most: Restores instantly — scuffs, grime, and dullness wiped away with zero effort. UV protection — living proof that it keeps vinyl from cracking, fading, or drying out under the sun. Non-greasy finish — no slick residue, just a clean, like-new surface. Multi-use — I’ve since used it on plastic trim and other surfaces. Same magic results. 💡 Pro Tip: Spray, let it sit for a few seconds, then wipe with a clean microfiber cloth. The before-and-after difference is jaw-dropping (see my photos!). If you’ve got a boat, jet ski, or any outdoor gear exposed to sun and weather, this product is a must. For me, it turned a “maybe we need new seats” moment into “wow, our pontoon looks like new again.” Highly recommend.

Excellent product Works well Arrived on time

If you have a bike with plastic fairing and you don't want the plastic to look faded and old, use this protectant. Its just an amazing way to make the plastic shine and to keep it dirt resistant. Every time I wash my bike, the first thing I do it after it dries is to apply this. Very happy with the protectant.

Just like what they have described

In my case it didnt work at all. Sprayed it on the travel bag and no results whatsoever. I recommend finding another solution if you have an extreme color fades like in my case

303 is the finest UV protectant out there. It truly works to protect a multitude of surfaces such as vinyl, plastic, rubber, and leather from the harmful effects of the sun. As it is non-silicone based, it is never sticky or overly glossy, drying to a semi-matte sheen. It is far superior to Armor All or Son-of-A-Gun - I stopped using these after I discovered 303.

Absolutely incredible for V-drums! So easy to use, just spray on, buff it in with an old rag and it’s comes out like new! I only used a minute amount. Highly recommended
