About 2-2.5 hrs to do an 01 Pathfinder. That's using a low pressure hose and washing, then rinsing each panel. After that, I sit on a mechanics rolling seat and clean all wheels by hand, along with the barrels using regular car wash, ONR, a brush, and one of those red cone looking brushes AG sells that look like Christmas trees on a stick. I dry using a leaf blower, then towels and some ONR mixture to keep off the water spots. I recently started mixing ONR with my regular car wash and noticed an odd reaction. The regular car wash no longer bubbles much and behaves just like ONR by itself. Little or no suds at all when mixing ONR with regular car wash. In fact, it acts almost like just ONR by itself, with no wash minus the color. It's a drastic difference in the wash media. Anyone else notice this? I'm always using ONR for a 2 bucket wash, as I think the surface is left much slicker and glossier than any cat wash.
