Well, it's been too cold to paint, so I haven't done any painting yet. I did strip the bike down, grease bearings (everything looks good there) polish the aluminum, pull off some non original stickers, and used some rubbing compound on the paint.
When/if it ever warms up, I think I'm going to hit up an automotive paint store and see if they can match my paint, and I'll just touch up the rusty parts. I may have it powdercoated later, but I don't think a spray paint job is what I want to do.
Thanks for for the advice on the gearing. I mostly plan to ride on the Loveland bike trail which is relatively flat, but regearing may be an option later.
