man...If I did 100 cpd I'd be $hitting gold bricks & not care I had 1 bad wash. I'd wash it again for free, dry it, Tire Shine, vacuum etc & count my money!
Fonic Power concentrate vs. K-R Vanilla Crème.
Vanilla Crème has good foam, GREAT smell, & slightly above avg cleaning
Fonic...I do not know. Price seems a lil less than V.C.
I think both you mix w/ 10 gallons of water, correct?
I give .10 off to the C-Store across the street. Hasn't gone real well, but do make $200/mo. Not worth it here, but will be a benefit for the guy who buys this wash.
