I did some research and decided on building a dedicated curing oven. Gunkote has molybdenum and acetone in it. Those things and all kinds of other stuff off-gas when you bake them. Over time, they build up on the surface of the oven. I don't want that stuff in my brownies, so I decided to build a curing oven. I used plans for a powdercoat oven and modified it. It's in its final phase of construction, but I think it'll work fine.
