What I have is an old convection oven. It was moms. We had a nice one so I took it to the shop as a small oven.
Bake or broil or Toast (both) with or without a fan. Has temp setting and time shutoff setting.
I hope to experiment with small things with power coating.
But cooking rods in a Bar-B-Que was me - I put the rods in vac bags. Then packed them into Tall Ammo cans.
When I open a can of rods, I put them into a Tall ammo can with rubber seal.
