Directions say to was motor and dry then spray on and wipe off...
So no need to rinse? Or use like regular gunk . Just trying to bring back some of the black to my cases on the deuce
After I wash my bike & dry it I usually just spray in on try to miss the chrome, but if I hit the chrome I wipe it off, otherwise just let it dry. Works great on mine.
Works great on my Deuce. Just make sure area you're treating is clean, dry & cool. If it's really dirty use a soft bristle brush, wash, rinse, dry.
Just spray on from4-6 inches just like you were painting.
