These were offmy salvaged 'bolt. There is no elongation of any of the holes, and none seem to be damaged - but they'e ugly, they currently have a coat of silver paint plus gunk. Anyone have any recommendations on giving them a new lease of life? How to clean? Can they be plated? What's the best way to really check for integrity? I have some penetrant red dye for crack testing welds, will that suffice?
