I concur. It's actually made by KG Industries. It's incredibly tuff stuff. I refinished my CZ 82 with it and couldn't be happier. I used the matte black color.
You did a good job. That CZ looks like a factory finish. I have read that cerra-coat is even better but is more difficult to apply.
I have actually just used spray paint for older less expensive guns in which I had to remove rust before finishing. The paint scratches easily but is also easy to retouch. Krylon seems to be a good one.
