I decided to clean up the fork lowers before I rebuilt them.  This was surprisingly easy and you could even do a better job if you spent more time.  I wet sanded them with 300,600,800,1000 grit papers using a 5g pail.  One sheet of each will work, just fold and tear and use each half for a separate fork leg.  I after i was done with sanding I took some mothers Aluminum and Mag polish and used a drill buffer wheel to polish.  They came out pretty well and I would say its about 2 hours total with some tunes going.  The pics show some of the progression and a comparison with the unfinished leg.

Looking good!
I do pretty much the same wet sand process, but just light polishing by hand for more of a brushed aluminum look.

I've still been working on this slowly when I have time.  The crank has been sent off to Chuck to work his magic on, so that will be in good shape soon.  I got both forks rebuilt and painted/cleaned up the rotor.  I ended up plastidiping the spokes and the hub on the front.  It actually came out decent.  I put a bt45 on the front and that was a PITA to get on (though lots of baby powder makes it not horrible), and I pinched a tube doing it.  :doh:  I put the new headset roller bearings in and started to put the forks on the frame just to get this project going somewhere.  I just need to get a rear tire and clean up the rear wheel and I can start putting the whole thing together.

I've read that some people do that, but others said they will still look dull. I figure I will leave them natural and see what happens.

I've still been working on this thing.  Chuck did outstanding work on the crank as you can see in the pictures.  Came back looking amazing and new.  The motor is sitting waiting to get sealed up, maybe tomorrow.  I also started getting the frame back together.  I put the rear tire on (BT45 110/80/18) but I can't seem to get one part of the bead to seat, thing was a pain to get on too.

Looks nice man! Especially considering how it sat outside... seems like you got it in the knick of time. I'll have to keep that dude in mind for when it comes down to my crank.

Soapy water lots of air pressure and beat the crap out of the sidewall with a big rubber mallet. That bead will slowly work itís way on rim.
