Ignition of ammonium perchlorate and aluminum

[TYRONEEZEKIEL]

I dont know if the corrosive nature of AP was resolved, but as far as storing goes, I keep mine in large plastic tubs with dessicant. I would be weary of storing it with anything metal, as from my experience it rusts it back to dust. I have cut AP stars with a razor blade, wiped it off with solvent, and have come back to a brown, dull, worthless piece of rusty junk.
