Wow, what timing. I was just going to post about this.
I picked up an oooooold two wheel grinder with a cloth buffing wheel on one side and a block of white polishing compound at a flea market yesterday. Got it all for $20 thinking I might try and polish up my solarezed lures. I got it home, plugged it in, put on some compound and sure enough it shined them right up! I would say they are at about 90% full gloss if that makes sense. If I had the know-how and maybe another wheel I'm sure I could bring them to a mirror shine but as they are now they are pretty darn near it. It took about a minute per lure after I got the hang of it.
