All you need now is buffing.
I use these with no blasting: http://products3.3m.com/catalog/us/...nd_AbcPageHandler/theme_us_electronicsesm_3_0
An angle die grinder on a fairly low to med speed and working with the finer grit discs will brighten the most cursty bolts. I have an Argentine Mauser that was covered on surface rust but now looks brand new thanks to some Roloc disc work.
I've been polishing my bolt work for over 7 years on a 3/4 hp buffer. This new finish is for the guy that doesn't want shiny on his hunting rifle. Those Rolec pads look pretty wild. I use stiff yellow buffing pads and two pound buffing compound sticks.
Ahhh, it see now... You're the boltman. I've seen your work and read posts about it on other forums. Parallax Bill's I think mainly.
For myself, being in the auto body field I have lots of tools and metal working goodies at my disposal including all kinds of sanding/grinding/buffing goodies. 3M and Norton both have a whole line of prep discs for angle die grinders. I refinished my Romanian AK bolt with one of the coarse maroon ones and even removed grind marks from machining with it.
What do you do for protection on the blasted bolts after? Being a hunting rifle I would think oils from someone's hand or moisture from the air would cause surface rust if they weren't treated after.

I usually cover the polished bolts with oil before I ship them out. I just bought a sandblasting cabinet today. I guess it will be a trial for me to see what happens. I will oil them up before shipping them out. That should protect them. I'm also thinking of doing some wild coatings maybe.
