Just want to share a good experience in buying sandpaper goods. I want to Gettysburg to visit an old friend & while there I stopped in at Red Hill Corporation. They sell mostly abrasives & have one helluva big shop full to the rafters. I bought & have used some of their materials with great satisfaction. Good prices. E.g., 3×21 sanding belts 10 for $10. 5inch PSA discs $21 for 100. If anyone needs to contact they can be reached at www.supergrit.com. E-mail – email@example.com. I was well treated by everyone there.
