I currently have a 7424 and the Poorboy polishes 3, 2.5, 1 and PWS. They work good and all but after reading alot about Menzerna I was thinking about getting some for my PC. My questions are do they work well with the PC and how much better are they over Poorboy's? I live in Oklahoma and work outside alot so are the Menzerna line sun friendly like the poorboy line? I am about to Zaino my truck and wifes car and would like to use a polish with no fillers to make sure the paint is in the best possible shape so I get the best results from Zaino. Thanks in advance, Mike...
