I always wash my own cars and like all have mentioned, it takes hours just to wash it. That's why i have yet to wax it and it's 3 years old

Kudos to HUMMER for excellent paint job because my paint still looks as good as it did 3 years ago
Btw, for those of you that haven't invest in one of those pressure washer, get it! It takes half the time, uses a lot less water, and does much better job. I also have a water softener at home so much less water spots. The only thing that worries me is the salt the softener uses
