Lots of you guys using Autofoam Bilt Hamber, I use it with a pressure washer and autobrite lance but don't find it that good, as in it doesn't seem very thick and comes off quickly. Haven't done a comparison though. My usual process is :
Cover in foam and then jet wash off usually leaving around 5 mins, I apply with the lance on maximum from the bottle and about 1:3, foam:water. Does this sound about right?
