Wow, thats a long time. I have a '02 Dakota club, and I can go to the self serve and have the outside done in an easy 20 minutes. Then when I get back home, a vacuum, run with the Swiffer duster, and a splash of Stoner I.G., and I can be done in an hour flat including the drive home.
And to get the roof. I open the door, lay down a towel, and stand on the sill. It doesn't hurt anything, you just have to be carefull with the water. The top rubber seal should keep water from draining it.
Here is how I do the outside...
The self serve give us 2 minutes with the sprayer.
I plunk in a buck and fill my bucket. By then I have an easy minute and a half and walk around the truck spraying top to bottom over and over, until it stops. Then I take a folded, soaked, soapy, wash mit and begin rubbing. With a total of 4 turns of the mit (all clean sides) I get the entire cab done. Re-dunk the mit and re-fold it, then do the box.
I then plunk in another dallor and rinse the entire truck...no more than 2 minutes has gone, and a fine mist is going through the air from the other people. Then I give the truck a farely thorough drying.
Then I take my second mit and do the wheels, since the paint is clean, I am not worried about the dirty water. After I finish the wheels, I do the wheel wells and under the rocker panels with a third mit.
Being carefull with the sprayer I give the wheels and underbody a final spray...Take the first towel and dry the wheels. Then I take a clean towel and dry spots I may have gotten with the sprayer. Then out the door I go.
Easy thorough winter wash for $3. Can't go wrong.
In the summer...It easily takes 4 hours to wash my truck...Funny how that is.
