nodrogkam: It took me over six hours to wash, clay bar, polish, and wax my car. It was probably closer to 7 yeally, and I was exhausted by the end of the day.
This is the only photo I have up right now that shows my entire car:

I bring my own bucket to the car wash because I don't like using those hairy brushes they have at the car wash where to soap comes out. I used it once and it smeared the dirt around and took really long to get the car reasonably clean. I think I spent about $15 worth of quarters that time. Every time after that I brought my own bucket and Meguiars Gold car wash and spent less than $5.
There was a car wash in town that had a spot free rinse mode that would spray water at lower pressure and didn't leave as many water spots, but that one is closed now. I think they probably filtered the water somehow.
I contemplated washing my car on base at the hobby shop, but I realized that if I did that, I would flood all the other bays since there isn't any drainage in the bays. I was flushing my radiator when I realized that the water would flood. Outside the bay it's slightly graded so that water drains, but the bays themselves are flat.
