I'm preparing a Super Mondia frame for powder coating, and the frame is in excellent condition, except.......

Apparently the head badge had come off, and was reattached using pop rivets. Remnants of the original bottom rivet are still in the frame, and a new hole was drilled right next to it. More accurately, it looks like they punched a hole in the frame because there is a pretty good indentation in the head tube where the new hole is. The dent is only about 1/2" diameter and only about 1/8" deep. If I can ever find another head badge, chances are, it will cover most of that dent, but in the meantime, I want to fill the hole.

Which brings me to my question. Can I powder coat over body filler? If so, is there a better kind to use? In a perfect world, I would have the dent pulled out and the holes brazed shut, but it has chrome-plated lugs, and I don't want them exposed to high temperatures. I'm looking for a 'room temperature' solution. I'm just not sure about the powder coating process, and if the powder will be attracted to body filler. There will be very little of it.
