ArmorAll Protectant VS 303 Protectant | Which is Better? | 

I used original Armor All in 1981 on some boat seats. They were still in good shape 10 years later when I sold the boat.

Price, fancy marketing claims on the label etc are all irrelevant. Look up the actual chemical ingredients for yourself to see what you are buying. The active ingredient in all UV protectants is silicone. It absorbs UV. The other additives are simply fragrances, surfactants etc The old armourall was solvent based. The new armourall formula is water based like the 303, so less toxic. 303 is the same as armourall. Just watered down. That's why it is less shiny. You can make 303 by diluting armourall with 5 parts water. 303 is mostly just very expensive water!

ArmorAll has had the stage for way to long and they finally decided to step it up but the problem is 303 is just much more advanced so my personal opinion is ArmorAll is junk and 303 is the future. Good luck!!
