Meguiars makes good stuff. You probably can't go wrong with any of their stuff. When I do have time to detail mine, I've been using Gold Class. Just this summer I thought I'd try something new and picked up a bottle of their polish, step #2 I think. Wow! Amazing stuff. Smells awesome too. Like bananas. Clean the car and dry it. Go over it with the polish and then wax over that and nice deep shine. I've got Gold Class liquid, the liquid polish, a tube of scratchx and a bottle of plastx. The plastx works good on the headlights, but I found that it also worked good on my wife's windshield on her last car. The previous owner never changed the wipers it appeared because there were "arches" etched into the glass. Daytime driving wasn't bad but nighttime with the headlights and street lights beaming off each line was like some hyperspace looking **** from Star Wars. I took a chance and buffed the windshield a few times with plastx and it made a difference. I recommend anything that you might try, try it first in an inconspicuous place first to see what it'll do. With the windsheild, I started in the lower corner of the passenger side, where the driver doesn't normally look out of to make sure I didn't make it worse.
Yeah, Meguiar's definately makes good stuff.
