Yep, crap shoot, they say anything that's not factory original will not be returned, but I know of several people who sent in Glocks with aftermarket internals and got them back the same.
Anyone who gives a negative review of Duracoat or claims that it comes off in any regard either A) Didn't know what they were doing when they applied it or B) They sent it to someone who didn't know what they were doing. Duracoat does not finish in a hardner type fashion like other pants, it is elastic to resist chipping and such. It is rock solid and when done right you literally have to go to war to get it off.I looked into Dura-coat, but read some mixed reviews online. Some said it has flaked our chief pretty fast. I asked on here a while back and several recommended getting it refinished by Glock. For $45, I figured that even if I didn't like the results, I could still have it done with something else later.
From what I understand they check everything out. I couldn't have it detail cleaned for $45 at a gun shop in Tampa, so this is a great deal.
Im gonna Duracoat my next one. Just because.
First off, Glock does nothing poorly, those people are dumb. Secondly again if the Duracoat came off he should get a refund from whoever claimed to know what they were doing. Last the Tennifer is a process in the metal and can not affect anything least of which Duracoat.I've heard some say that the "re-finish" job that Glock does is poorly done and wears off quickly. I have never seen one done personally though. A friend had his gen 1 G21 slide duracoated. It began wearing off quickly. I wonder if the tennifer finish has something to do with affecting the duracoat from adhering properly.
