Aluma Hyde? How well has it worked for you?

As I think back, I washed my aluminum upper with brake parts cleaner, pre-warmed it, and sprayed a very light coat. When it dried, like a half hour, I sprayed another final cover coat and placed it in the oven at 150F. I let it cool to the touch with the oven door open and was done.
I've only airbrushed DuraCoat or Cerakote since then, so don't know if it's changed any in 24 years.

Brownell’s has very specific directions on preparation, spraying and subsequent coats. Definitely need to shake it well . Warm clean parts and then heat curing makes it a very durable finish. Although it takes a while to fully cure it did not run or stay sticky that long.

Ok, I think I'm getting the hang of it. This stuff does take quite awhile to cure, I checked it again on saturday and the former soft spots seemed to be solid and bonded. I lightly sanded it with 320 grit and applied another coat, I'll let it dry for 10 days and then touch up any areas that need it.
