Love the Black Hole. As far as sealant, have not used one with BH. But did put a layer of Pinnacle Souveran over BH, nice look. Any PB product I have tried, I have liked very much.
As far as wheel cleaner, which does not require much agitation, Try PB's Spray and Rinse wheel cleaner. Pretty strong stuff. And the tire gel, my favorite is Pinnacle Black Onyx.:buffing:Im the MAN
Have read on here, some people having trouble with the sheepskin. I have had mine going on 2 summers now, and no problems. Have the bone, but have not used it with ONR. Works great with regular car wash.
