Matter of personal preference, I would say. Brush would give you a thicker coat I suppose but I think a spray can would be easier.
Some people use high temp grill paint, some use regular spray paint. If you are just using it for smoking, regular spray paint would be fine. It really shouldn't get hot enough to hurt regular spray paint.
But accidents do happen.
If you leave the lid off a little too long it can get quite hot.
I've seen some that weren't painted at all. The owner just sprayed the outside with Pam and cooked with it. After several cooks, the outside was glossy black. Pretty amazing really.
I used Duplicolor Hi Heat Engine Enamel on mine. Two coats of primer on bare metal followed by three coats of Daytona Yellow.
Certainly not necessary but it was fun.
I've gotten the drum pretty darn hot. I set the expanded metal rack that I use occasionally right on top of the charcoal basket to burn the grease buildup off of it. Got hot enough to discolor the bottom third of the drum slightly right about the level of the charcoal basket. Was WAY hotter than it would ever be smoking or even grilling. Paint didn't come off though, just got a little darker.
