[ARC5] Rebuild or No: A Poll

[Glenn Little WB4UIV]

In the case of the holes, I would not use filler.
I would ensure the holes are round and plug the holes with the same 
material as the case and the same thickness.
The plugs would be welded in place.
When properly sanded and refinished, it would take a very close 
inspection to see that the holes ever existed.
