Shinkers

Sorry to bring up an old thread, but there's some very good info here.

I do have a couple of questions though. I'll be getting a raw al. (unicycle) frame this week that I plan to polish up. It's already brushed, and I bought some 600-2000 wet/dry sandpaper and Mothers.

My first question is, how hard is it to deal with welds? Welds and cable guides are where I'm most concerned about sanding. I'm just not sure how hard it'll be to sand dimpled areas like the welds and tight spots.

My next question is, I've heard about wet sanding with minereal spirits, and also vegetable oil, along with just plain water. I had planned on using just water, but is there something better?

And has anyone finished polishing with just the Mothers (no wax or protectants)? How did it hold up as far as corrosion goes?

Is there anyway that all the sanding could somehow weaken the frame?

I'm hoping this is an idiot-proof process because if there's a way to screw it up, usually I try to find it.

Thanks!
