Here's Incredible Proof 303 Works

The left side of the vest in the picture below was treated once with 303 Aerospace Protectant. After 35,000 hours in the hot California sun and rain, the side treated with the 303 looks nearly brand new while the untreated side has almost totally deteriorated. 303 works on just about anything and can save you literally 100's of dollars. As much as tennis shoes cost today, think about how much longer they will last treated with 303? 303 Aerospace Protectant keeps UV-sensitive materials "like new" year after year!

Just Who Uses & Recommends 303?

Because of its enduring cosmetic properties, the resistance of 303-treated surfaces to dust, soiling, and staining, its water repellency and unparalleled protective characteristics, manufacturers worldwide recommend 303 Aerospace Protectant. 303 Aerospace Protectant is the only name in protection for hundreds of manufacturers including the world's largest. The growing list includes:

One of the largest suppliers of vinyl and leather to the marine industry. MSG/G&T recommends only 303 and advises their customers not to use other protectant products.

One of the world's largest manufacturers of automotive convertible tops and supplier not only to the `big three' U.S.automakers but others worldwide. AMCO specifies 303 Aerospace Protectant for its vinyl tops. Other top and cover manufacturers recommending 303 are KAYLINE, BESTOP, COLGAN CUSTOM, SPORT MASTERS and DOWNEY PRODUCTS.


AMCO Manufacturing Corporation

I wanted to take a moment to thank you for your fabulous product, 303 Aerospace Protectant, and to explain how "303" has benefited our company since we discovered it.

As you know, AMCO Manufacturing Corporation is the world's largest manufacturer of convertible tops. For over twenty years, AMCO has supplied both vinyl and fabric convertible tops to the U.S. car makers as well as to the major car manufacturers of Europe, Asia and Latin America. AMCO has recommended 303 Aerospace Protectant for its vinyl tops ever since our major vinyl supplier tested 303 in their labs and verified its amazing properties.

With respect to AMCO's aftermarket line, by now recommending only 303 Aerospace Protectant in AMCO's care instructions, we are minimizing the uninformed use of name brand "protectant" or "vinyl treatment" products, particularly those containing known degradents such as silicone oils, petroleum distillates, alcohol, etc. Accordingly, we expect our customers to experience added years of service and performance from every AMCO convertible top vinyl top.

Of course 303 Aerospace Protectant lasts many times longer than other available protectants, and as test show, is the most powerful UV screening protective product on the market. With 303 we expect AMCO vinyl tops will stay looking like new, year after year. Personally for me (and anyone else I've met who has tried 303). I will use nothing else on vinyl, rubber, plastic, fiberglass and leather surfaces of everything I own.

Thanks for manufacturing a vinyl protectant that really protects. 303 truly is "The World's Best".

Thanks for a great product!
Hi my name is Randy Broughton and I wanted to say, "Thanks for coming up with a great vinyl product." I've tried every vinyl treatment product on the market and they all leave my 1966 Mustang vinyl feeling sticky. When I'm at a car show it has to look it's best because everyone wants to touch the outside of my car so that they can see that it is real. Now that I have found 303, this years car show will be even better. I won't have to keep applying treatment all day long just to keep a shine and it won't have that sticky feeling to it....My Mustang is a one of a kind.. it is covered with vinyl on the entire outside, no paint. So you see I need the best. Can't wait till the shows start back up.

Just wanted to let you know how much I love to use 303 Aerospace Protectant on every vinyl and rubber piece on my car. Everything from the dashboard and weather stripping to the hoses in my engine bay. 303 Aerospace Protectant leaves a nice shine, that lasts, on whatever I put it on without having that greasy look. I usually give my car a thorough cleaning three times a year, and when people see my car they think I clean three times a month! I recommend 303 Aerospace Protectant to everyone I know.
