So I have a 1987 944 Turbo. Replacing the gasket on the oil pan. I was told to remove the gasket material left on the pan and block with Roloc discs. I found at the auto store there are the bristle type and the pads. So having never used these I am nervous as you know what about damaging the surface..... What have others used to clean these surfaces. The engine is in the car by the way
