| I have a gas tube and a slab side magazine that are parterized and I want them to be blued. How dod I remove the parkerizing? Chemicals? Media blasting? |
You do not have to remove the Parkerizing unless you want a polished finish. If you want matte blue, just clean it up and cold-blue it. Or hot-blue if you have the set-up. If the Park'ing is in poor shape with uncovered areas, well yes, blast it first. Another easy fix is to spray and bake with Brownell's Gun Kote 'Matte Black'. You would only have to degrease it first. That's what's on these gas tubes:

Just wondering, why? Everything except the gas tube is blued. I love the look and just want to make the gas tube match the rest of the rifle. Not too bad of a match but I would prefer it all matches. 
Magazine is not so important. I'll try the blue over the park and see how it works. |

| It might be painted - they have that, you know. Obviously the blue wouldn't take on paint. I have blackened many Parkerized parts with cold blue. Next time you try it, don't use chemical degreasers - use hot water and dish soap. The part can still be soapy when you take a clean toothbrush (not one you ever used for gun oil or bore cleaner) and start scrubbing it with the blue. In fact, the soap helps the process. You will get a build-up which will rub/wash off, and you have to remove this (similar to 'carding' in rust-bluing). Repeat this process until the right depth of black is achieved. You always have to use soap and water to remove the build-up after application so you can see what you have. Breakfree CLP is great as an after-oil. |

Good luck getting that to match without rebluing the whole rifle. Thanks, I don't think it could have matched much better after a blast, good cleaning and a little cold blue. Not an absolute perfect match but nothing blued separately or different metals ever matches perfectly. Looks much better than when it was parked.

'They have paint? When did they invent that?' Very funny. I meant they have Parkerizing-color paint. Hey, that is a heluva job you did on that gas tube! How did you clean it? l Just giving you a little crap about the paint. First I gave it a cleaning with brake cleaner, then blasted it to remove the park, then a little scrub with a green scotch bright pad, then another brake cleaner spray, then Birchwood Casey blue and rust remover (just for kicks), then Birchwood Casey cleaner-degreaser, then twice with the cold blue.
I decided to leave the magazine parked. |
