I use Zymol (blue bottle, smells like suntan lotion) on my small scratches. You can get it at PepBoys or AutoZone. It's not a wax, it's a car polish and it's good. I just wish I had the energy to polish the entire car.
I've also used a wax made by Busch. I looked and they don't have a website but you can order their color waxes from http://www.accessconnect.com
or qualitytire.com. This stuff is awesome
, I used the white wax on my ride and it is GREAT. I'm ordering some after I finish this up.
