> Motul's Wash & Wax spray
So something like this?
My bad. I like motul's wash and wax. Definitely keep it off the seat, it's pretty slick
There is a wash/shine spray-on that Harley and Motul make I've used on my bike. Works fairly well with just a microfiber towel on fiberglass and chrome. For water, you can use a garden pump sprayer with distilled bottled water from the store. Some links:
