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

Marine Aerospace Protectant Spray delivers long‑lasting UV and weather protection for your boat, RV, or outdoor gear. Its advanced formulation helps protect vinyl, rubber, plastic, and gelcoat from fading, cracking, and harsh sun exposure — ideal for marine environments where salt and sunlight can take a toll. It sprays on easily and dries without leaving a greasy residue, giving surfaces a clean, refreshed look while enhancing durability. Perfect for dashboards, seats, trim, and exterior surfaces exposed to sun and salt air. Pros: • Strong UV and weather protection • Non‑greasy finish • Easy to apply Cons: • Best results with regular re‑application • Scent may be noticeable initially Bottom Line: A reliable protectant spray that keeps marine and outdoor surfaces looking newer longer — a smart choice for boat owners and outdoor enthusiasts.

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 conditioner and preserveative for rubber. Use it to protect scuba gear before extended storage. Looks just like new when its next used.

My Go-To UV Protectant for All RV Exterior Plastics and Rubber 303 Marine UV Protectant has earned a permanent spot in my RV maintenance kit and gets a well-deserved 5 stars every time. Living in Las Vegas where the sun is relentless and UV damage is a very real threat to exterior plastics, rubber seals, trim, and vinyl, having a reliable protectant that actually works is not optional—it's essential. I use this on virtually all of my RV exterior plastics and rubber components, and the difference in how surfaces look and hold up over time is very noticeable. It goes on clean, doesn't leave a greasy or slippery residue, and gives a natural-looking finish that repels UV rays and prevents the fading, cracking, and drying out that the desert sun causes on untreated surfaces. The 32 oz trigger sprayer makes application quick and easy, covering large surface areas efficiently without wasting product. The marine-grade formula gives extra confidence that it's built to handle tough outdoor conditions beyond just RV use—boats, patio furniture, and other outdoor equipment benefit equally. If you own an RV and want to protect your investment from sun damage, especially in hot climates, this is the one product I'd recommend above all others. Don't skip it.

I’m so happy I bought this product! Used on my copper outdoor lights, garage doors and painted metal door. It’s amazing how spiffy the joint looks not thanks to 303!!!!

I finally cleaned and vacuumed the car. The car was desperate for a cleaning by this point. Then I applied this vinyl conditioner and protector to all the needed areas: dashboard, console, gear shift, all vinyl and plastic areas in the back seat portion of the car. Wow. It brought those areas back to like new condition. This was a good and wise purchase on my part. I intend to use this conditioner/protector on my car every time a cleaning is due. I'll use this stuff till the bottle runs dry, and my car will love it and thank me for it. Has anyone else ever noticed that your car seems to run better once it's been thoroughly cleaned and pampered?? Well my car does. Do I recommend this product?? 200% Absolutely, yes. If in doubt, you can't go wrong with this product. ~Verified Customer

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.

I’ve been using this product on my boat’s seats and it’s kept them in great shape. It is important to apply with a cloth then use a microfiber cloth to buff. The more you buff, the better the protection and you will notice a slight shine. It takes more time than the vinyl products that only require wiping the product off but in my opinion, those products just don’t provide enough protection.

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.

So far so good. Happy for purchase but need time to see if it’s worth the price

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

Wow. This is really good. Put some shine on the metal parts of my boat. Seats look really good too.
