Too sand them I just started with a really rough grit sand paper. I think I had something like 100? I don't remember lol

Just get something rough so you can get a strong grip on the tips. Scratch them a bit and you'll start to see silver. Make sure your wetsanding too, just have a cup of water next to you and dip the sand paper in.

Then I went up in grit. I tried 800 next and it got smoother and shinier. Also I was wetsanding at this part too. Then I moved to 2000 and it got smoother and shinier. You can polish too and go the whole 9 yards, but I stopped at 2000 grit and I like em. Just gotta keep them clean because they will turn black again lol. You can just wipe em off.
