Frequently Asked Questions
What is 320 grit sandpaper used for in auto body?
320 grit is commonly used for sanding primer surfacer, feather-edging body filler and primer edges, and preparing surfaces for sealer application. It removes material faster than finer grits while still leaving a smooth enough scratch pattern for most sealers and primers.
Can I use this sandpaper wet and dry?
Yes, 3M Wetordry sheets are designed for both methods. Dry sanding at 320 grit is common for primer work, while wet sanding can be used for finer control.
How many sheets come in a pack?
Each pack of 3M 02040 contains 50 sheets measuring 9" x 11".
