Hello together who has got me a tip for the following problem. If I get my motorbikes out of the trailer, then a slide is required. The screen printing plates are so smooth that the mopeds slide down from the trailer even when the front brake is pulled, until now it has gone well every time, but it is a hell of a feeling to conduct such a motorcycle backwards without being able to brake until the rear wheel comes to the asphalt. How can I coat the floor plates so that the Is there any material for spraying, brushing or something else?
