303 was named 303 because it ws the 303rd reformulation of the product since during the development phase by the two Aerospace Chemists who came up with it.
The Aerospace Chemists that wanted something to keep expensive commercial airliner graphics from fading out...some companies like Alaskan, Virgin Atlantic, Quantas, JAL spent upwards of $150,000.00 to $250,000 on their paint (also called 'livery'), and didn't want it to fade out after a year!
It works as advertised....it's like slathering on a suntan lotion with a SPF of 42 on your paint, fiberglass, vinyl graphics, rubber, vinyl, plastics, etc. Keeps your tires from cracking from ozone damage, keeps your vinyl graphics from fading and curling up, keeps the plastic vents from yellowing, and contains no harmful petroleum products or silicones. Also for us RVers...keeps fiberglass, ABS Plastics, Vinyl Awnings, membrane roofing, tires and much more safe and new.
It is classified as a "GRASS" chemical..."Generally Regarded As Safe" with nothing harmful. It contains no Silicone. Enviornmentally safe too.
If anyone says anything in the formula has been changed...I'm sure it comes as a suprise to the Aerospace 303 guys, who say that it is the original formula.
Why tamper with something that is used by virtually all commercial and private air transport companies, the Navys Blue Angels, is proven to keep vinyl from fading and cracking 4 times longe....and is so safe that the only issue possible per the MSDS "slight eye irritation" COULD occur if splashed.
In my experience on RV applications using on tires, vinyl awnings, abs plastic trims, vinyl et al is a sure way to keep your RV and other vehices looking new.
