Three cans is the amount i used :P
i still half like half of a can that i could use for touch ups aswell,
I dont know about cleaning products,
i know i found it kinda annoying to clean just cause you have to take time and be more gentle so that you dont rip the coating.

base of plasti dip so you can remove the finish any time, but over it use any color enamel you want then a nice clear coat. gives you basically infinite color options plus the option of easily reverting back if you get bored. plus you wouldn't have to worry about cleaning chemicals or being gentle on the wheels when washing.
