I'm exactly the same, I try new products on the girlfriends car first
I've got a tub of the new ValetPro Artemis paste wax to try, her car has currently got Dodo Juice Hard Candy on but i'll strip this off and try the Artemis.
The Poorboy's wheel sealant is ok, you should try the blue Natty's paste wax, now that is good enough to eat
