This was the spray ceramic from Adam's. Started using it on the cars last year and love it. I've washed my truck 2-3 times, by hand (not a car wash) since applying it the first time and it still beads up well. I'll do a full clean and a new coat before winter. The tractor was super dirty. Broke one of the backhoe hydraulic lines a few week ago, made quite a mess. I did a quick clean then. I've also been screening compost that I use when overseeing parts of the lawn...did 4 yards. Been some dusty mowing in August as well. My wife had the pressure washer out, so I said what the hell. Got our some soap and a brush and used the widest nozzle and cleaned her up. The nice thing about the ceramic if that you can really put it everywhere, metal or plastic, etc. I figure it will help make those light cleanings a bit easier. especially with leaf season coming up. Always gotta blow her off after each use, this should just help the tractor be cleaner with less effort.
