So because it's finals week and I need a break... I am doing more write ups and test. This time I'm testing Aluma-Hyde II in Coyote. Here's my first write-up of Gun-Kote: Brownell's Gun-Kote test - AR15.COM

I used the handguard as a test subject and then a Pmag as my first actual piece.
Application: Sprayed the parts down with carb cleaner prior to paint. I heated the parts up with a heat gun before spraying and heated the pieces between coats. After about 4 coats, I let them dry for 30 minutes then in the oven they go.
Curing: I bake them at 200 degrees for 4 hours. It's best to use Convection setting in your oven because it blows hot AIR to dry and cure the Aluma-Hyde II. After that I let the pieces sit outside in the ambient air (45 degrees) for 15.
Strengthening finish: I used Turtle Wax and Carnu-B to polish both pieces. This gave it a smoother finish and made the finish more resistance to scratches.
Test: I scratched vigiously with my nails with no result. I scratch the handguard with a coin and it shows a little wear by giving off a shinny area. Knife did the trick and successfully removed the coat... along with some plastic. I put the Magpul Pmag into the well until it locked...15 times. I doesn't show any sign of wear. Note that the Turtle Wax and Carnu-B made the pieces slightly shinnier than the Matte finish but made it much stronger. I took the picutures below after all the tests.
Duration: Brownells say it takes several days to cure. People says it takes several weeks. I say it takes 5 hours.

thats what i figured but i was wondering about the cooking of the polymer and the bonding to the polymer

Honestly man, I wouldn't even try this on metal because of how well the Gun-Kote works. It bonds with the metal and has a low profile as oppose to this which is a very thick layer. My initial concern was that it's not going into my OA mag well easily.
