Review: 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.
Review: 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.

## Questions & Answers

**Q: Is this the best product to clean and protect the interior (dash/console/arm rest)of your vehicle?**
A: Many years ago at different car and collector shows, I asked around what these owners used, and unanimously the same answer was, '303 UV Protectant', and 'Klasse All in One Car Wax'. The trick to 303 use, is to lather on a generous coat, let sit a few minutes to soak in, than wipe off excess. This 303 is, Premium UV protection for car interiors, outdoor furniture and especially beneficial for boats and canvas. Anything exposed to the suns destructive UV rays, will benefit from this 303 protection. 09/2019

**Q: Is this a cleaner and conditioner as well? Does something need to be used prior?**
A: If you read on the back of the bottle, it recommends a cleaner prior to using, especially if the object is dirty already.  They make a cleaner as well.

**Q: Can you use this to protect the vinyl graphics on a Mini Cooper?**
A: yes . . .303 works on rubber based products and vinyl based products. you will be pleased with the protection it provides to keep the color of your vinyl.  It is the best product I have used to protect the tires, interiors and vinyl pin stripes of my cars.

**Q: anyone use it on chevy avalanche cladding**
A: I'll echo the other answers submitted so far.  I've had great luck with my Avalanche using 303.  I use Westley's (Black Magic) Bleach White to clean the plastics.  This does a nice job of stripping away dirt, debris, light oxidation, etc while leaving a nearly perfect surface for cleaning.  I use 303 for the cladding, bed covers, side plastics, weather stripping, door panels, console, dash, etc.  Basically, any rubber, plastic, vinyl, or similar surfaces get this treatment.  And as Echosyn pointed out, allow your floormats time to completely dry as they do get very slippery.  Good luck!

### ⭐⭐⭐⭐⭐ Pontoon Seat Savior – This Stuff Works!
*by S***N on September 18, 2025*

“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.
