A1 Nano Scratch Polish removes scratches using the latest nanotechnology. It removes scratches lastingly, instead of just covering them over. Its special nanotechnology polishing agents have an extremely even particle size, and break down into ever smaller nanoparticles during the polishing process. Scratches are eliminated without new, fine scratches being polished in. That creates a highly brilliant surface and depth to the colour. And all that in only one step. A1 Nano Scratch Polish is silicon free and suitable for use with polishing machines.
