Just some more tidbit I didn't see mentioned but like Hayaku mentioned, it's all subjective
The key to keeping your car great after polishing is a high quality car wash / clean wash mitts & drying towels/technique. It's the *lubricity* of a good car wash for me. While ALOT of griots stuff is overpriced, their car wash is really a good value for the gallon. It used to be $30 a gallon but due to their vendor material pricing going up, it's up to $40 a gallon. It's not the suds that count but the lubricity. I've been known to use the lead blower to dry the car to avoid any micro marring.
Besides keeping the car clean, a waxed car get's us out of speeding tickets. Don't belive me - Click
