Could you please elaborate on your working space, Ben?
Does the entire room get covered in powder? Can you do it indoors (think apartment)? How much mess does it make?
I do it in the garage. It can make a mess so if you are doing it inside you can spray in a cardboard box to minimize it. The mess is just powder dust so it wipes off easily and vacuums/sweeps up no problem. You can do it outside but make sure the wind won't blow your powder off the enclosure.
Basically I take the raw enclosure and wipe it down with acetone until noote black stuff comes off on the paper towel. Then I bake the enclosure for 15 minutes at about 385. This gets any last oils or fibers off. It also prewarms the enclosure which promotes powder adhesion
Then I fire up the powder rig and spray the enclosures. You have to ensure they are grounded to the rig. You can tape a grounding wire to them with the heat proof tape or I use my stand rig (Thanks Cody!) to ground it.
A light coat of dust will adhere to the enclosure based on static attraction. Pay attention to get the edges and sides completely covered.
You then will carefully move it to the oven without bumping it or disturbing the powder. Bake at about 385F for 15-20 minutes after "flow out". If you want you can take the enclosure out after 10 minutes while the powder is "wet" and spray it again to ensure coverage.
After the 15-20 minutes is done, you are done! As soon as the enclosure cools you can do whatever you want to it. Easy peasy. The dust can make a mess but it's not smelly whatsoever.
