yes I’m sorry, i was typing while on a phone con....trying to multi task...but yes you may wish to wipe it off but you don't have to.
In about an hour it will dry and the plastic will actually absorb the plasticizer which is contained in the Black Magic.
I use the paint brush method, it works great! But you will need to have a very clean car.
Not only will it fix any odd sounds coming from plastic rubbing plastic but it will also give your car that new car smell!
Only drawback…your window…gets hazy
