Hmmm...very interesting results.
All seven people that have voted as of now have done so for AIO, yet Klasse advertises that this product (excluding any very recent changes) has remained the same since 1979, with all fourteen ingredients remaining the same.
Klasse: "Klasse All In One Polish will remove oxidation, minor swirls, and other surface blemishes; leaving a beautiful and deep acrylic shine."
On the other hand, Meguiars released their ColorX product in late '03, some 24 years later...you would think over two decades of development and technology would result in a superior product?
"Meguiar’s COLORx is a liquid polish and wax combination formulated to remove slight scratches and swirls, remove oxidation and blemishes that dull paint finish, and lock in the shine of restored deep color and revived gloss."
