Great Conditioner & Sealant that Nobody knows about. Simply the Best!
If you don't know about Formula 303 SEALANT/Shine you should. Conditions plastic & rubber much better than any other available product. With use when new, inside & out & regular every 3 months re-apolication, 3x the miles on your tires is normal. I've seen 156k miles tires treated with 303 & they look but& have the look, grip & tread as newly mounted tires but look far better due to 303 conditioning. This is NOT like typical but"rubber or plastic shine" type auto products. It SEALS & treats the raw open rubber on belts, hoses & tires making them far stronger & harder lessening the wear immensely. I use it on anything plastic or rubber on my vehicles & reapply every 3 months. Unlike other products (Armor all etc.) It does NOT stain glass or plastic & won't make sun baked surfaces crack (dashboards etc.) if only used 1x. I reapply it inside & outside my vehicles to deepen the color of rubber & plastic. May be used on dyed or painted plastic bumpers or boat painted fiberglass without damaging the paint or dye. Great for hard to reach seals & any rubber that sees wear on vehicles. I soak my belts & hoses & tie rod or ball joints for instance overnight or for 20 minutes pre i installation & it reduces wear. Great in CV boots as well & prevents tearing due to age without adding a shiny,greasy feeling to the item. Used it 1x on a dashboard now with 170k+ miles on it. No cracks now & looks better than new. Hasn't stained any fabric, paint or metal unlike other rubber treatment products. Save serious $ & use on your tires & get 109k+ miles from them even if you use this on only the outside (let it soak in overnight on 1st application imho & for 6-8 hours every 3-4 months after just by spraying them down with 303. Also works great as a leather restirer & sealant). The Gallon is a "must have" for me & easily the cheapest buy. 303 is definitely much better than any other treatment & truly aerospace & aviation designed to protect $100k aviation cockpit dashboards from the sun. Nothing else comes close. I've been using it for over 25 years without a single disappoinment & find new uses all the time as it is a sealant/protectant + it + standard household spray paint may be used to recondition worn dyed color leather seats easily & cheaply with no paint ever coming off on your clothes after using 303 sealant. It's simply the best leather, rubber,fiberglass & plastic conditioner & sealant made.

Great product.
I use this on a lot of stuff from fiberglass, plastic to auto paint! Great for a quick cleanup and shine. It does repel dust.

You have to try it
I had a mobile fleet washing and detail business for over 20 years. I had accounts with the California Highway Patrol for over 10 years. I’ve tried so many products usually 3M is my go too. But I have to say this is probably one of the best protectants I’ve ever used. I haven’t tried it out in the blistering heat that we have in the summer. But as far as aplying this product and removing is so easy. And the look it leaves is amazing. Now I’ve only used it on vinyl but it’s incredible! You definitely have to try it. Another thing I was amazed with is the small amount I used and the area it covered.

My Go-To UV Protectant for All RV Exterior Plastics and Rubber
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.

Not just for boats
I was looking for something to bring my Polaris back to life. It’s not that old, but considering I use it very often I sometimes forget to put it in the garage. (Leaving it to sit out all day long in the baking sun.) I came across this boat protection and figured it’s the same concept that i was looking for. Something that would protect the interior and exterior of my side by side from fading in the sun. I have to say it’s pretty good stuff. It’s sort of like another type of a car brand that starts with an “A.” However, I’d have to say I think better. It doesn’t leave nearly as bad streaks for one and if you do happen to get any streaks just take your micro cloth and rub in circles and they easily disappear. You also don’t see that messy “ start and end point” you get from other products. (When the sun hits it and your able to see every place you didn’t get.) Everything seems to blend in very smoothly and looks uniform and much newer. As you can see from my photo pretty much every area is done except the floors and a couple other areas.) It suggests not doing the floors, but I’m going to do them anyways, just not the petals. This stuff really rejuvenated my buggy! (I didn’t even wash it all that good at first like the instructions suggested. One other thing that I liked is that it seems like it will last much longer than previous brands because it doesn’t feel like it’s sitting on the surface of everything. Even though everything is nice and shiny and new looking it’s not slippery. Nor does it feel like it’s right on top of the surface. I’m super happy I came across this and decided to give it a try. It’s perfect for any automobile or just about anything that you want to protect from sun fading. 😎

Best Product
The best marine upholstery protection. Tried several products and this one stands out, by far.

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

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.
