I've used it 2x with not so good success, as have many others. I have refinished many firearms, with everything from hot blue, to wally world rattle-can.
Troy, I'm not picking an e-fight with you but I'll say that something must have gone wrong.
I've done over 1K weapons and thousands of parts an pieces, non gun items etc. I've never had a coating failure of any kind.
My personal pistol had at 1K draws from a kydex holster with no wear on the slide before I re coated it. It's now close to that again.
I'd love to see or hear what your problem with it was.
Heck even Bambam has switched to it.
It just didn't harden up well either time. I followed the directions to the letter.
Dura coat is garbage, use Cerakote. I've seen duracoat rust, wear, etc. Cerakote on the other won't. The ceramic is a far superior product
