I tried the ES method and while it works ok, I found it quite tedious and well, a PIA balancing bullets on top of nuts and all. Base down they don't all get covered well where needed, with some requiring a 2nd coat. Nose down of course only works with a large meplat.
Just as a quickie test, last night I swirled a half dozen bullets in a small container with a splash of HF red and after just a minute or two, they were well coated. Dumped 'em on the same tray I used for ES, except I didn't use a new sheet of ns foil, put in the oven for 10min @ 400 and they came out very well. In spite of the fact that they stuck to the preexisting paint on the tray (I pulled 'em off while still very hot), the coverage was surprisingly good. Will definitely be working on better trays, screens etc, whatever works out the best. I'm a much happier camper.
BTW. I got a
Hamilton Beach convection oven from Walmart for $60. It's quite large and can take up to 4 trays. The thermostat is fairly accurate. Now if only I can figure out what the rotisserie might be useful for...
