FAQs about P500

What is P500 sandpaper used for?

Fine primer sanding: Fine sanding of primer surfacer, plastics before painting. Typical for Car & paint, Primer.

Is P500 coarse or fine?

P500 belongs to the very fine range (P500 to P1000): keying paint. The higher the number, the finer the grit.

Which grit comes after P500?

After P500 comes P600. Never more than double the number per step – that way the finer grit removes the scratches of the coarser one.

Should P500 be used wet or dry?

Dry, with dust extraction – up to about P600 that is the standard today: faster, and no water in the metal or wood. Mesh discs and multi-hole patterns stop P500 from clogging.

Which grit comes before P500?

Before P500, sand with P400 (or finer). Jump straight to P500 from too coarse a grit and you won't get the scratches out.
