My son do detail work for some of our friends with high end cars as well as pamper our own 66 mustang coupe, 78 alfa romeo spider and recently acquired 300 ce coupe (wife' car that I get to drive) we have tried them all and we swear by P21s wax and paintwork cleaner. Since our garage queens do not sit outside, we only use the P21s paintwork cleaner. This is a fine-non abrasive polish that gives an incredible shine with concours results. If you need to use wax, one coat of their wax will last 2-3 months and goes on and comes off like a dream with no residue...give it a try, you to will be a believer.
