I have used the Duracoat stuff and was very unhappy with it. It chips and scratches just like regular paint. Therefore, I am not using it anymore. We went to great lengths to see that we did the job with the Duracoat just like the directions stated. We warmed the pices up, made sure there sas no oil or dirt on every piece. Then after several months of curing, they still chipped and scratched. One trip and the gun looks like it has been beat with stones the way the coating has come off. No better than the coating last I feel it is too expensive.
To be honest Rustolium seems to be more durable. Rog
