DuracoatAerosol Kit (ACU Grey Green)

I've used DuraCoat finish on a dozen or so of my firearms and it's a great product. It's very easy to work with. Just follow the directions. Allow the coating to cure properly. It's dry to touch in several hours depending on your environment and technically, a firearm can be used 24 hours later although the full curing time can be about 4 weeks. Best to do it right, let it sit for the 4 weeks in controlled humidity and temperature. I tested my latest handgun and the finish came clean with no carbon impregnated or discoloration.
