Speaking of this, I got all my pads and some other stuff from Motor Head (doh, I shouldn't be saying that here) for my DeWalt polisher and I saw their little magazine, they have the one brand of wax for 1099.99, another for 349.00 and the rest are the usual 20.00 waxes.
They have wax for import cars
They have wax for spoilers and wings
I don't know, if you ask me the wax for specific parts of the cars kinda of seem bull. I'm going to have all this car wash, polish, glaze, polymers and then 20 different types of wax. I'll be there all day waxing a car with a few aftermarket peices and end up using 30 terry pads.
