How would you polish a flat bottomed receiver in the lathe? Not to jump in Docs' way here, but, I've never seen a "high gloss" slow rust blue. I guess that doesn't mean it doesn't exist. The 'subdued' look is just the nature of the beast, from what know about it. I've slow rust blued for 20 years and have tried many different preps and several different formulas. Polish it out to 400-600 grit and give it a dip in a hot , caustic tank, and it might blind ya'!X Ring Accuracy said:Your gunsmith should be able to "polish" the action, lug, barrel, once the machining work is done. If he can't, pick another smith. The point is when the parts are in a lathe, then is the time to do it. I know of polishing wheels, etc. We do all of our polishing on a barrel, action, etc in a lathe. Makes for a better product. Just our .02
