Question about pressure washers my shop is in a quiet residential area across the street from the local u wash. I normally drive the cars across the street and wash them there it cost about $3.00 I simply use the high pressure to spray the car off then I hand wash with my wash mitt and bucket then rinse again. I thought about getting a cheap electric PW and riging it up to my water tank with a sure flo water pump. any Ideas about this would be most helpful.
