Rated 3 out of 5 by All Pro Vinyl Graphic oh from Magic pad applicator for rivots It’s good for basic, flat trailer rivots. Also, the larger rear roll down doors trailer doors. If u have a case where the trailers rivots have been replaced with the small torque screws, the brush really isn’t dense or thick press the vinyl down to cover the sides of those small screws. Now if the made a denser version, it would make doing rivots 5xs faster for the installer!
