Making a 30 y/o set of wheels new.
It took multiple sessions of sanding and polishing, each of which I came out looking like the tin man from the amount of aluminum dust. But I can say they’re 99.9% perfect.
After building a polishing jig, powder coating, valve stems, decals, and other misc expenses, I probably saved a couple hundred bucks over buying a brand new set. Was it worth it? Hell yes! I learned a lot and the ‘vintage factor’ is priceless.
