Hey guys! I'm new to forum. I recently dug out an old pair of x-squared x-metal Oakleys from a moving box I hadn't touched in years. I had cast them aside due to scratched lenses and being tired of having my vision obstructed. Imagine my shock when I saw them going for $5oo+ on ebay... Holy smokes. BUT, they're in rough shape. So... I'm wanting to do a full restoration on them myself, I'm not concerned about tackling this project as I build guitars and other custom instruments professionally, and have a background in machining and welding. The stops that prevent the ear stems have worn, causing the tips to scratch the lenses when folded. Has anyone else patched these with a TIG? I'll include photos below. My concerns are: Will powdercoating the frames affect the value if I want to sell in the future? Also: Is the ear stem problem common and are there accepted ways to repair it? Thanks guys!
