I bought one of these to wash my wife’s black Lexus. It’s pricey but zero water spots even washing in hot sun. No drying required. Use it on my gray Maverick also. No water spots.

My Michelins came from the dealer at 37 psi. The factory recommendation on the door panel is 35 psi. Thinking about going to 32 psi for a smoother ride.
