1 Year Coating Test Koch chemie GSX Rinseless RRW Wk11

1 Year Coating Test Koch-chemie GSX Rinseless RRW Wk11 Using Koch-Chemie RRW 45ml in 12 liters ns 30ml of Gentle snow foam Xmas edition. I think GSF has been getting a little bit of a hard time due to the high output pressure washers. My prefer is not to go upto a 3 gpm machine but stay at a 1.5 gpm Ryobi 1000psi ( when I use it). Most of the time I’m preferring a foamer as it much lowere in cost and less foam in the driveway. As it stands Week 11 see no changes using balanced PH soaps.
