I have a G26 EXO as well. It's my off duty weapon, and has held up great so far. I was never interested in this stuff until I got a Fail Zero coated BCG for my AR. When shooting it suppressed, the coated BCG makes a huge difference. One day I was looking around at the local shop and I came across the EXO G26 they had. The next day I bought it and have been very pleased.
While I'm sure CCR and the like are great coatings, I had a negative experience with a well known coating company (not CCR) a few years ago. The end result was fine, but the turn around time was WAY off, not to mention a few lies here and there. That single experience has forced me not to send off anything again, unless it's to the manufacturer for a warranty problem.
