I have used it a lot. It is more thick than Duracoat, which I now use, so I never used it in areas where tolerances could be affected. Also, even after cured, Lock-Tite will damage it causing it to peel. I used it on barrels, flash suppressors, stocks-both plastic and wood, and upper and lower receivers. But as I said, holes for pins had to be blocked and threads protected.
Out of the can and allowed to air dry takes a week or more so I baked mine at 200*F for 2 hours to cure so you must be sure your part will take the heat. If heated too hot the finish will blister so watch it. And baking in the oven stinks the place up to high heaven so ventilate very well. It’s fairly durable, fairly easy to touch up, but be sure to buy clear out nozzles and extra spray nozzles too. I always clear the spray tube before starting to spray and use a new, clean spray nozzle for each spraying session. If you try to reuse a spray nozzle it will spray clumps, even if you clear the nozzle after use. That happened several times to me before I wised up and used a new spray nozzle each time.
And be sure to keep that can well shaken. Pause to shake it every minute or so of spraying. I liked it a lot but when my son bought me an air brush, I switched to Duracoat and never looked back. I still use Aluma-Hyde II for quick small jobs but it is not as durable as Duracoat.
