I checked Autozone, best they had was 3M 2000 grit. Was going to check Murray's Discount...

Also, do they just come in packs of 25? Doubtful that I'll need that much, just wanted to fix a couple of chips and scratches that touched up.

Thanks!

FYI - I'm in a northern suburb of Chicago, if that helps.

 

I found the best selection over the internet, a quick Google Shopping search should land a few hits.
