Norton Prosand Sandpaper -  20 Sheets [80 Coarse Grit]

The Norton 3X abrasive sheet offers more durability over an uncoated abrasive while resisting chip loading.

This sheet is used for paint stripping, sanding and finishing on composites and fiberglass, and all-purpose bare wood sanding.

Coated abrasives have individual abrasive grains spaced at a predetermined distance from one another.

An open coat covers about 50 to 70 percent of the coated surface with abrasive, for greater flexibility and resistance to clogging than a closed coat, which has 100 percent grain coverage.

An open coat allows for longer usage time by clogging less, while a closed coat offers a finer surface finish than an equivalent open-coat abrasive.
