See the 'facts' for yourself. Do a search for "Insert Name" msds found here:

Original Protectant - Armor All

See what it contains:
Non hazardous silicone emulsion 5-15%
Other non hazardous ingredients 5%
Water to 100%

And then, comparing to 303 (for which there are several different products):


This product is classified as a HAZARDOUS SUBSTANCE and as DANGEROUS GOODS according to the classification criteria of NOHSC: 1008 (2004)and ADG Code (Australia). The Ingredients? "Propietary"

"303 Aerospace Protectant™ does not contain any harmful silicone oils, which can dry out and damage surfaces."

From the instructions: "

Out of direct sun, spray surface with 303 Aerospace Protectant™ and WIPE COMPLETELY DRY. If streaking occurs, too much product has been used. Use a wet towel to remove excess, IMMEDIATELY WIPE COMPLETELY DRY. Note: this product does not air dry. Extra buffing with a dry cloth INCREASES bonding, repellency & longevity. "

Bold text is the original from the mfg.

303 is not a wax. It's a UV protectant - and it works as such. We've used it for many, many years with excellent results and it doesn't wash off. It lasts quite a while.

We've also used it on the Diamond Shield for 10 years and it still looks new.

I lost track of the general intent here - commenting i guess?

I likes my 303 for plastic and vinyl stuff. Def is not a consistency like the old AA stuff. Has achieved recommending to coworker level of cred, too. My intro was away from the RV world and in the detailing world. Still.

If a $20 is a tough leap, then look at it this way - you'll pay half that much for AA, but 1974 won't show up asking for their nostalgic goo back.

I've used 303 for the past 4 years and buy it from CW by the gallon when its on sale. Everything plastic and rubber gets applications after washings.
