Grigg, I'd try asking some body shops how they deal with it.
I'm sure they've run into it with owners using it on the rubber or the black facia trim and it ends up on the part they need to paint.
Your rig looks great right down to the heavy duty hitch receiver. You must have some plans to pull something. So, hows it run out.
Been tempted to take it down the road a ways yet ?
