Mr.SURFACER 1500 contains finer granules than Mr.SURFACER 1000. They are both used in much the same way but due to the finer granules after sanding with waterproof sand-paper, a perfectly corrected surface is possible. This is a Pink version of the Finishing Surfacer. This Pink base allows the omission of the painting of a light coat before applying a color and reduces the thickness of painting.
