If you have the one from chis at GGD, I use the grey or blue one I think. Depending on the tip it'll run thru the soap pretty quick. I do maybe a 1/8 of soap and that's it. I rinse the truck down with water first real good, the sud up the whole truck let it sit for a sec, rinse, and then foam a section at a time as I wash it.

I put 3-4 cap full's of soap in, and then take the hose and fill the tank real slow so it doesn't bubble up. Like tast said i rinse down real good then i foam, rinse, re foam, and wash.
