Maybe someone has posted this before, or thought of this before.... but this is my mega cheap and effective oven for baking on "Engine enamel", could be used to speed/help cure any paint I suppose. With VHT or Dupli-color engine enamel you are required to Bake it on at roughly 200 degrees for about an hour. It is as simple as it looks, a 35 gallon steel trash can with a hole cut in the bottom, and a hairdryer crammed in and taped up to help seal it. Parts hang off eye bolt from the lid. With the hairdryer on high, and some of the air escaping etc, it somehow keeps a steady temperature between 175 and 190. Maybe a little less than ideal temp, I just leave parts in a little longer. I also have a bunch of duct tape around rim of can to help seal lid better and I use some cheap duct tape to tape around lid to seal air in while parts are baking.
