I would tape the inside of the hole, apply filler and remove the tape and sand to a smooth finish once it's dry. It's surprisingly durable, particularly effective at the smaller holes obviously. One warning is, don't try bake dry the paint on an enclosure that's been filled... trust me on this![]()
I tend to use the same technique, but I use a product called JB Weld. Though i dont think you will have a problem with heat with JB Weld (they do have a high heat version too
