I've been doing the ONR 2 bucket methods for years now but I was wondering if there are other alternatives...came across this
http://www.amazon.com/Ivation-Multip...s=CAR+WASH+12V
wondering if anybody here has seen or heard of it. looks promising.
UPDATE
I ended up just buying the damn thing. It does a great job knocking out loose dirt and grime off the car. I only use it to pre-rinse...I still do my ONR but this thing cuts my wash time in half.
