This spring I bought the step 1,2,and 3 red bottles of meg's paint system. (cleaner wax, deep crystal polish, and something else). Don't waste your money. So much work for hardly any difference.
www.detailedimage.com has some awesome packages that they bundle together to kind of take the guess work out of it. I'm waiting until I get my Porter Cable 7424 before I go buying all the polishes and waxes. Right now, I only do a 2 bucket wash, claybar, cleaner wax, and Ice. I don't reccommend the Ice as anything that will last. But I wash my car about twice a week, so I just take the extra 10 minutes and apply it when needed. I also need to dust off the car every morning, since that Turtle Wax Ice is like a magnet for dust, pollen, etc.
Eventually I'm going to invest in a selection of mainly Menzerna, Poorboy's, and Zaino products. I've only heard good things about them, but they are expensive.
JWerner, which Zymol product do you use?
