As I look on line I couldn't find any posts on polishing stainless bolts. So here is how I polished mine. I went to Harbor Freight and bought a 1in by 30in belt sander to use to grind the letters off the bolts, I used a 80 grit belt at first until the head of the bolt was void of all letters and flat. Then I switched the belt out for a 120 grit and sanded the head flat and made sure all of the low spots and imperfections were gone. After that I used 320 grit sheet paper on a flat surface to sand out the 120 scratches by hand. I know that doing it by hand is a lot more work but I found the end result looked better. there are other ways to sand the heads of bolts using a electric drill just make sure you don't over tighten the drill on the bolts and tare up the threads or to loose and spin the bolt. The problem I have with using a drill is that unless you a really careful it will leave circles in the head of the bolt. After the 320 grit I used 400, then 600 and finally 1200 to finish the sanding process. For polishing I first used 3M rubbing compound Perfect-it on a clean piece of paper and used one drop and rubbed it vigorously rotating the bolt a quarter turn periodically. After polishing with the Perfect-it I used a clean micro fiber rag to lightly buff the bolt to a shine. A few of the bolts I had to work back and forth on different grits of paper to work out small scratches but in the end I thought they turned out great!
