.22lr..."I wouldn't expect a phone rep to have the test specs sitting right in front of them"
expect a phone rep to have the information available to him/her but he didn't because there is no testing info for duracoat available.
.22lr...."I find dismising a product due to its inferior testing (which has not been shown), based on a single phone conversation, silly"
In my post, I stated that I did research it. My decision to not use duracoat was not based on a single phone conversation but was due to the lack of results from some fairly detailed research. What my research did turn up, were consistant rumors and allegations that duracoat was never designed for firearms as their advertising states. It was designed for farm machinery by Sherwin Williams and is called Polane. Now that doesn't mean it's a bad finish but it sure does explain two things. Why there's no tests of it on firearms and why it can't be used on firearm internals. It's too thick.

The testing program for Gunkote was conducted in two stages. The first was a submergence test in assorted chemicals. This was conducted for Armscor in South Africa by the South African Naval Logistics Department. Test results are at the end of my post. The second part of the process was real life. This was conducted by the South African Navy and the US Navy Seal Teams. The end result is that Gunkote is now required by the miltaries of several countries on certain weapons systems. Note: The test results below show how long the Gunkote'd material was in the chemical before any notable deterioration occured.
22lr..."feel free to post the test results of your product"
Gunkote is not my product. (I wish it was!) I use Gunkote as the second and third coats in our Tuff-Gun finish. Our Tuff-Gun finish is not a finish. It's a process that I have developed in thirty plus years of experience with Gunkote. Even our trade name "Tuff-Gun" refer's to the process.
22lr...."the supposed lack of testing could be hiding the fact that the Dura/Gunkote products to be superior"
