Anyone out there use Dykem to mark cases?

UPDATE:

Turns out, spinning the cases while applying the stain didn't work. When the dyed brass falls onto my drying mat, whatever it touches takes the stain off the brass.

I tumbled and cleaned the brass well with denatured alcohol and put it in a gallon-sized Ziploc. Splashing in about .5 to .75 oz of dye and shaking the bag worked better than anything else I tried.

The problem is there's still splotchy areas on the brass (often an entire side of a case) that won't "take" the dye. It looks/acts like it's oily, but the alcohol should've fixed that.

Also, the dye DOES come off during tumbling, but not all of it. Applying more will only lead to build-up that could make the brass too thick to be usable. So, I had to clean the brass with alcohol after tumbling to apply more dye, which I WON'T do after each use (too much fuss).

All-in-all, I'm NOT considering the Dykem idea a complete bust. It works as well as a Sharpie, but is messy. I'll just use it to mark the headstamp to make my sorting easier and go back to hoping I find it all before someone else sweeps it up at the range.
