The problem is most all of this stuff is little more than high tech paint. Paint chips with rough handling. This is why I put off purchasing my CZ 75 until I found one in polished Stainless Steel. I've never seen one in high polish blue, which would have been acceptable. I didn't want one in Black Polycoat because it is little more than paint. Most of the CZ's I've seen that have had any kind of rough handling or holster wear with the Polycoat really deteriorated appearance wise.
It's much the same with a lot of these camo finishes. They look fantastic out of the box. But cleaning solvents, handling, holster wear, and just about everything else a gun comes into contact with will take their toll over time. They are just not as durable as a blued finish, or any of the commercial metal finishes like NP-3 from Robar. But for fixing up a sick looking AK, they do offer the home gunsmith a inexpensive solution, besides having to look at a ratty gun all the time. At least for a while.
