Anybody have experience with Zep Truck and Trailer Wash? I know that it is pretty basic in pH, I think it could be a good solution for a presoak before paint polishing. The other day I only had the time to foam a pretty dirty car, so some stubborn traffic film remained after 2oz Purple Power Boat & RV, 1/2oz BF Foam Booster, and 1oz Mineral Spirits in the foam cannon. Anybody think that Zep`s product could get us closer to a true touchless wash without getting into the chemicals that Semi Truck Washers that aren`t as commercially available?

What about Zep Professional Touchless Foaming Car/Truck Detergent?
