When I paint jigs I use a heat gun and count (1001, 1002, etc) for every jig. That keeps me constant. I only get the jig hot enough for a light dull coat of paint, just enough to cover the head. That way I don’t get runs.
For a rack to hang jigs on, I took a grill rack from an old cheap grill I had in the camper and cut it down to fit over the top of a baking pan that I bought from Wal Mart. It has 3 rows and can easily handle 2 dozen bass jigs at a time. When baking is done I pull the pan out and set it on the garage floor to cool.
I have been using this setup for at least 20 years.
