Tried the pro 12 a
"Tried the pro 12 a few days ago. A buddy gave me a bottle of car wash that he had extra. I couldn’t get it to foam, just soapy water. It called for 1 oz for 5 gal of water. Tried all 3 tubes and none work. Fully pressurized and clean filter. The wash was called mr pink made by chemical guys. Maybe I’m doing something wrong. Any help would be appreciated. Thank you"
