This is a black version of the Finishing Surfacer. This black base gives you a very thin and fine base for paint, fills ultra fine sanding scratches, and also allows the omission of the painting of a black coat before applying a metallic color and reduces the thickness of painting. This surfacer can be applied to give a final finish to the surface and gives a semi-gloss appearance. It has the characteristic of being fine grained and it is not prone to clogging up detail in the model while still being able to flow, level, and fill micro scratches giving a surface equivalent to sanding with 1500 sandpaper.
