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.
