Had a chance to try out the rapid dirt shifter tonight. Car is still protected with toughcoat, beading is not very uniform but sheeting well.
car rinsed with a normal hose, then rds sprayed undiluted liberally over all panels. Left to dwell for 3minutes before some areas looked lime they were starting to dry then pressure rinsed with my baby c110.
general dirt seemed to lift quite well but wouldn't really attack the dried bug splatter or heavy dirt spots unless constantly hit with the pressure washer. Carwas then left to dry to see how clean the panels were, and if im honest they weren't quite as clean as I'd normally get with citrus power. More comparable to diluted 1:1 CP that I tend to use. Certainly comparable to the majority of snowfoams I've used.
after the usual wash routine, I didnt think it was really beading and sheeting all that well. Are we sure this is LSP safe? Will test in the morning as dew beads off the bonnet as we pull onto the bypass.
overal, for the cost its a great pre wash, a little further testing required to determine how safe it is. Plan to try it diluted and an inch in the bottom of a snowfoam
