I found this is on a detailing website after a Yahoo search of "Autopia" (just wanted to see who else was using the name). According to this website most of us should just quit our detailing and start paying professionals. Here's an excert from their FAQ:
"Q: I wash my vehicle at home using a garden hose?
A: Washing your vehicle at home is extremely harmful to the finish. The University of Texas proved that a single home hand-wash can leave scratches in your finish as deep as 1/10 of the paints total thickness. Also, the average garden hose cannot supply enough water and water pressure with the detergent action to avoid damaging a vehicle's finish.
This important study concluded that automobile owners should avoid washing their vehicles at home. Only a professional car wash can provide the proper amounts of water and water pressure needed along with the appropriate soaps and waxes to safely and effectively clean your vehicle."
Interesting technique to scare people away from washing their own cars...just thought it was funny.
