The kit allows you to pre-polish to make headlights transparent or to sand motorcycle plastics before painting. The grain remains durable and the paper does not get soggy even after several minutes in water. With this product, you can easily erase small scratches on the car body. You could also use these sheets on wood using the grains from the coarsest to the finest without skipping steps. This way, the sanding time per grain is fast and the result obtained is exemplary. Note that due to batch issues, the color may be slightly different from the image, but the size and granularity are the same.
