Fellow Hiders' -
As is common on the web, certain questions and requests are posed over and over. Two that come to mind on firearms-related sites are <span style="font-style: italic">"What is the best coating?"</span>, or <span style="font-style: italic">"What should I coat gun in?"</span> Obviously, which coating you chose is dependent upon what your objective is concerning the coating. Is your interest cosmetic-only, or are you looking for wear and corrosion-resistance? What about lubricity? Are you interested in coating the whole weapon, or just the contact areas?
Some coatings are great for corrosion resistance, some for wear resistance, and others for lubricity. Few excel at everything. NP3 / NiCorr are great for internal parts, but you don't coat the whole gun in it, do you? If you want something that you can coat the entire weapon in - inside and out, you want a Birdsong "T"-finish.
So what is "Birdsong", and what is so good about? <span style="font-weight: bold"><span style="font-style: italic">Birdsong Black-T</span></span> was developed by the late Walter E. Birdsong more than 30 years ago. Walter died last year, but his son Wally has been at the helm of <span style="font-weight: bold"><span style="font-style: italic">W.E. Birdsong & Associates</span></span> since Walter's passing.
Birdsong "T"-finishes are proprietary, meaning that Birdsong - <span style="font-style: italic">and only Birdsong</span>, applies Birdsong finishes. The various formulations and application procedure are highly secret, which is why only Birdsong applies their coatings. Anyone who claims to apply Birdsong other than the Birdsong shop is FOS, period. Shops have to send in firearms, tools, ect. for coating just like anyone else.
The U.S. government has been after Birdsong's formula for decades, but Birdsong has always steadfastly refused to disclose their formula and application procedures.
The downside to Birdsong coating is the leadtime - as Birdsong (rightly) gives priority to Military / Special Teams, and LEO. Since Birdsong holds a lot of goverment contracts, civilian coating jobs can be pushed back when large contracts come in. However, Birdsong finishes are well worth the wait.
<span style="font-weight: bold"><span style="font-style: italic">Black-T</span></span>, the original formulation, has been in use for more than 30 years and is the choice of many Federal and municipal agencies - Birdsong is used exclusively by Tac Ops, and Tac Ops alone has supplied roughly six hundred (600) agencies worldwide, including the Los Angeles branch of a certain alphabet agency that protects the POTUS. It is in use by elite teams such as the U.S.N. SEALs'.
<span style="font-weight: bold"><span style="font-style: italic">Black-T</span></span> is applied very thin - only .0002-.0003 thick (about 1/10th of the thickness of most other teflon/polymer finishes). It bonds very well, can be applied to both ferrous and non-ferrous metals, and is extremely resistant to salt spray and chemicals as well as being very slick. Birdsong actually recommends that no lubricant is used on Birdsong-coated parts.
Because Birdsong finishes are so thin, slick, and stick so well they are applied to every part, both inside and out. Even the tiniest springs and screws are coated, further helping to prevent corrosion. Birdsong finishing includes complete disassembly, prep, coating, and re-assembly. And you can trust Birdsong implicitly with your valuable firearms.
Other Birdsong formulations include two types of Green-T (<span style="font-style: italic">"Tac Ops OD" Green-T</span> and <span style="font-style: italic">"Naval Special Warfare" Green-T</span>), plus <span style="font-style: italic">Tan-T</span> and <span style="font-style: italic">Brown-T</span>. The original Green-T is very OD in color and is now known as <span style="font-weight: bold"><span style="font-style: italic">Tac Ops OD</span></span>. "Tac Ops OD" Green-T used to be available to the public but is now exclusive to Tac Ops customers.
The newer <span style="font-style: italic">"Naval Special Warfare"</span> Green-T is what is applied to non-Tac Ops work that is sent in for Green-T coating. <span style="font-style: italic">"Naval Special Warfare"</span> Green-T was developed specifically for the U.S.N. and has some brown is it's formulation, but it appears quite green by itself. However, when viewed alongside Tac Ops OD Green-T it appears more brownish.
I said "appears" because, like everything - the color and appearance of Birdsong finishes is affected by light. Light intensity and color, perspective, and backlight all affect what the eye "sees". And even if a photo is representative of what the color seen in person is, <span style="font-weight: bold"><span style="font-style: italic">it is only valid for that particular lighting condition</span></span>.
Also, <span style="font-weight: bold"><span style="font-style: italic">Birdsong finishes</span></span> never stop hardening, and they tend to darken a bit as they age and continue to harden. That said, below are a few photos of Birdsong Tac Ops Green-T and Birdsong Naval Special Warfare Green-T. I currently do not have any photos of Tan-T (closest to FDE) or Brown-T.
