The 3M Hookit Gold Disc is a precision-coated abrasive disc designed for professional auto body sanding and finishing applications. This 6-inch P400 grit disc features aluminum oxide mineral abrasive on lightweight A-weight paper backing, delivering a sharp, aggressive cut with a uniform, consistent finish ideal for primer sanding, fine featheredging, and paint preparation.

Key Features:

• Premium aluminum oxide abrasive combines fast cutting action with extended disc life
• Open coat construction resists loading and allows efficient dust evacuation
• Load-resistant coating prevents clogging when sanding primers and paints
• Multi-hole pattern facilitates dust extraction for longer disc life and cleaner finishes
• Hookit hook-and-loop backing enables easy attachment, removal, and reuse throughout abrasive life
• A-weight paper backing provides flexibility for contour sanding and fine finishing work

The Hookit attachment system allows these discs to be quickly attached to compatible backup pads on random orbital sanders, removed cleanly, and reused multiple times. The P400 grit is ideal for applications including primer sanding, paint scuffing, and final surface preparation before painting. Works on clear coat, fiberglass, paint, primer, plastic, and SMC substrates. Each box contains 100 discs.
