If done properly, Duracoat is extremely durable.
Seems some are confusing the "paint pen" with the Aluminum Black in a bottle similar to their Perma Blue product. The Aluminum Black is a chemical process similar to cold bluing, and results in like manner depend a lot on preparation. It's essentially an acid which will lightly etch and darken aluminum - I use it regularly to touch up those little dings you get in AR receivers and parts and it generally turns out well. Not sure I'd try an entire gun, frame, receiver, etc. with it unless I felt like I was able to get them completely clean to the bare metal and had a container large enough and with enough solution to fully submerge them.
The aluminum black is clear. You put it on and have to wait for the chemical reaction to occur. Again, I've had great results with it.Seems some are confusing the "paint pen" with the Aluminum Black in a bottle similar to their Perma Blue product.

Duracoat it yourself. I do all my own stuff.
