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: 303 Protectant Really Works!! - 303 Protectant is the best treatment for gaskets, tires and untreated matt black plastics when detailing cars and trucks. It doesn’t turn the tires brown after UV exposure, keeps the gaskets soft and pliable plus enriches the look of the matt black, unpainted molding/trim. Also it can be used sparingly. A 32 oz spray bottle goes a long way when used on a pad or small soft microfiber towel. I think it’s a great product!

## Questions & Answers

**Q: Can it be used in nylon rope?**
A: Not sure why as it would make it slippery and nylon is already pretty impervious to the elements.

**Q: I use spray paint to create faux stained glass, but it fades in direct sunlight. Can this be used to protect the color?**
A: This multi-purpose detailing spray restores and maintains a like-new appearance, texture, and color on a variety of surfaces including vinyl, plastic, synthetic and natural rubber, PVC, metal, gel coat, fiberglass, stainless steel, and more.  So not sure about glass.  I don't think it would hurt it, but it may be worth a try?!?!?

**Q: Can it be used on outdoor wood/teak furniture?**
A: Because of the different types of wood and tweak finishes, it is not recommended. To get a more specific answer, please feel free to contact Gold Eagle directly. Hope this was useful!

**Q: Is this a low gloss product?**
A: Low gloss, certainly.

### ⭐⭐⭐⭐⭐ Helps protect and shine
*by S***C on July 9, 2025*

This stuff is great. We use it on our resin Adirondack chairs as well as our hot tub cover. It cleans it up nicely and lasts a few weeks to a month, nice and shiny. It helps protect from the sun. We have been using it for years now. Easy to use and not really an odor to it. I think it’s a good value for keeping our furniture looking nice. We have also used it on our plastic shutters up north and it shines them right up. They recommend using it every 3 weeks I believe
