I have a color problem with my upper and lower (grey/black). Has anyone ever used US Anodizing inc.? I'm planning on buying the XTREMCOAT™ TEFLON OVEN CURE COATING--4 OZ (Flat Black) and the AIR BRUSH KIT ($65 shipped). Has anyone ever done this on their own? If so how did it come out? www.usanodizing.com/products.htm |
| I used KG Gunkote from Brownells to do an upper and lower in Dark Earth and it looked great, but I didn't have the equipment to abrasive blast the surface first so I don't expect it to be quite as durable as it could be. A lot of people use Duracoat (available from Lauer) in part because you don't have to bake it and have good success. I've never used the XTREMECOAT, but I'm sure its similar to Duracoat, and probably very high quality. Try inquiring in the rifinishing forum in the Armory section, probably get some good help there. |

As far as the anodizing that they do, the general concensus is that they are good. As far as the Extremecoat product that they make, I purchased it, have used it according to their instructions(including preheating the parts to be sprayed), and am not impressed with the results. The color match to most black anodized receivers is excellent, however it hasn't worn well for me on non-moving parts. After reading the spec sheet, it appears very similar to Birdsong Black-T, but I haven't used that so I can't say for sure. |
What do you mean by "however it hasn't worn well for me on non-moving parts."? Did it chip or anything, how does it hold up over time? |
It chips, and when contacted by other metal, and it has worn where the upper meets the lower after only a few hundred rounds. I'm using an accuwedge, so there's no slop between the two. Not sure about it "sealing" moving parts together. |
I've wondered about the effects of sand or bead-blasting anodized aluminum gun parts. As I understand it, when aluminum is anodized, the surface structure of the metal is altered and becomes harder. If this is true, blasting could possibly remove this outside "shell" of hardened material, exposing the softer aluminum underneath. Of course, it depends on how deep this hardening goes into the aluminum. Perhaps someone who understands anodizing could comment. |
