Ok I compared 303, Vinylex, and Armor All
I applied them and let them sit for a few minutes.
The 303 quickly hazed down from the original shine to the dull level you'll see in a min.
The Vinylex stayed pretty shinny. It may have gotten slightly duller.
The armor all actually wax less shinny than Vinylex.
When I felt them you could not tell a difference between undressed dash and dash dressing with 303 Aerospace. Truly awesome!
Vinylex was slightly more slippery. I don't think it left a greasy residue on my hand but I think it would be enough to attract dust.
The Armor All was super greasy and left a greasing feeling on my fingers.
Here are the pics. Hard to tell a difference but you can see how 303 has hazed down. The are from left to right.
