I just need to do my rotors... I thought you only had to let it sit a few hours and then you are good to go.
It would depend on the paint you use. Some paint maybe dry to the touch in 30 mins but cure in 24 hours. Look at the directions on the paint you use.
I let it sit for almost a day if using G2 since it cures in 24 hours. Also if the paint is not dry, turning the wheels at speed may throw some paint, or if you pick up small stones it could score the paint.
Check the paint you are planning to use. It's paint dependant. I would gladly help you out.
