303® Marine Aerospace Protectant - 32oz, 30306

I`ve used many surface protectants over the years, all silicone based, and this stuff outperforms it by a mile.I have a roller shutter which covers the bed of my pickup. It has a vinyl finish that is relatively vulnerable to winds and weathers but an occasional wipe over with the 303 and nothing can stick to it.

Arrived quickly and seems to work well on hot tub cover with heavy weather exposure. Time will tell

This helps to prolong the life of many items we have which are subject to constant attack from the sun.

Good quality protectant for my Tonneau cover on covering my open-bed on my ranger. I just cleaned with power washer and moderately dried the cover before applying using a thin relatively absorbent cloth to wipe/buffer the protectant after lightly spraying the cover a section at a time. One week later a shine is still present and no issues with either build-up or sticky mechanisms. Easy to apply. Instructions state to use sparingly which is a good thing as the protectant is a little expensive but you receive nearly 1 litre so the bottle will last a while for the average user unless you have a large inflatable/boat to protect. I have also used on plastic/rubber seals by applying to a cloth first and then applying to insure the solution is applied correctly and not on glass.

Very Satisfied.

Exactly what I needed.

Yep, that's a shocking cliche, but when it comes to dressing the plastics found in car interiors & engine bays, this is the best product I've ever used. If you've not tried it before, get it on.

Best Marine protectant

This stuff is brilliant. Protects boat seats far beyond what I expected. Will buy this again

I an impress my slide out were getting drie and my awning started to have bubbles after treating all twice my slide out has tighten up and softer my awning no more bubbles and has also tighten up. Make sure to clean them before applying the 303. I used for cleaning dawn platinum with that little duck

“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.

Great product! I bought it for the side steps of my 4wd. It's not slippery at all and rejuvenates the black well. Clean the area well beforehand and let it dry. Polish in properly.
