I began powder coating several years ago. I bought some colors from All Powder Paints. I think I bought a pound of green, red, blue, and black. These paints were stored in Mason jars in my garage. May have gotten fairly warm in the summers here in South Carolina.
I used the appropriate #5 containers, and the proper black airsoft bb's. A few shakes, and life was good! My Mihec 9mm bullets stopped leading.
Then, something CHANGED! My paint wouldn't stick any more. I tried adding styrofoam to the container, pre-heating the bullets, high humidity days, low humidity days, new bb's, fresh paint, putting my containers in a vibrating cleaner, washing the bullets in acetone, and even tried several spells I learned in Haiti. I could not get any powder to stick.
So, I order some fresh powder. I ordered from Powder by the Pound this time, by mistake (I forgot who I used last time). The fresh powder puts me back in a happy place!
I can only assume the powder got too warm in the garage or got old.
Has anyone else experienced this?
