I really must be doing something wrong then cause I get through a whole deluted bottle easy, sometimes when im only half way around the car! Ive took my lance apart and cleaned and checked for blockage etc. I think I need to mess about with both the end nozzle and the pos/neg valve on the top to see if I can get better results.
Ive now got Valet Pro orange to try and ive got myself a pump sprayer to apply it. I thought it would be easier than getting all the kit out to snow foam each wash.
