Review on 303 Marine Aerospace Protectant - Superior UV Protection - Enhances Longevity of Vinyl, Rubber, and Plastic - 16 fl. oz. (30340CSR) by Philip Anderson

If you don't know Formula 303 SEALANT/Shine, you should. Contains plastic and rubber much better than any other product available. When used new, inside and out, and regularly changed every 3 months, a 3-fold increase in the mileage of your tires is normal. I've seen 156,000 mile tires treated with 303 and they look but have the feel, grip and tread of freshly fitted tires but look a lot better due to the 303 conditioning. These are not typical "rubber or plastic gloss" type automotive products. . SEALS and treats raw, exposed rubber on belts, tubes and tires, making them much stronger and stiffer and significantly reducing wear. I use it on all plastic or rubber surfaces on my cars and reapply every 3 months. Unlike other products (Armor for All, etc.) it will NOT discolor glass or plastic and will NOT crack on sunburned surfaces (dashboards, etc.) with a single use. I reapply it inside and outside my cars to deepen the color of rubber and plastic. Can be used on painted or painted plastic boat bumpers or painted fiberglass without damaging the paint or dye. Ideal for hard-to-reach seals and rubber that wears out on vehicles. For example, I soak belts, hoses, tie rods or ball joints overnight or 20 minutes before installation, which reduces wear. Also great for CV boots and will prevent age related cracking without giving the product a shiny and greasy feel. I used it 1 time on the dash now it has over 170,000 miles on it. No cracks, looks better than new. Will not stain fabric, paint or metal unlike other rubber treatment products. Save big money and use it on your tires and get over 109,000 miles out of it even if you only use it outside (imho let it soak overnight for the first use and for 6-8 hours every 3-4 months thereafter just spray below with 303. Also works great as a leather refresher and sealer). The gallon is a "must have" for me and by far the cheapest purchase. The 303 is definitely way better than any other treatment and truly aerospace, designed to protect the dashboards of a $100,000 airplane cockpit from the sun. Nothing else comes close. I've been using it for over 25 years without a single disappointment and I keep finding new uses as it's a sealer/protector + it + standard household spray paint can be used to restore worn colored leather seats easily and inexpensively at no cost. Color has ever come off your clothes after using Sealant 303. It is simply the best care and sealant for leather, rubber, fiberglass and plastic.
