Rust

Any suggestions on what to do with frame rust? I have a little rust in a lot of places on my CroMo MTB. Thanks!

Wax.
(I had to try a short response too. )
Really, waxing with carnauba or similar wax will seal the rust(provided it is not real deep) and waterproof it. If it is beyond mere light film, then you will want to use a product similar to Extend to treat and stabilize it. Then, depending on your goal, paint and wax it when it is cured. Keep in mind, however, that when you do wax you will not be able to paint that area without a lot of cleaning.

Was thinking more along the lines of touchup paint,but I ain't a rocket scientist. Maybe even clear fingernail polish.

You need to remove the rust first so get a steel pad or some fine emery paper and keep rubbing till the rust is gone, then go to a model store and buy Testors paint that will closely match the paint you have and just touch up the spot you sanded. If your really picky about the color match you can sample a small dab of paint on the bottom of your bottom bracket shell, wait for paint dry and see how it looks, keep adjusting color till you like it.

Hell, I'd just use a wire brush in a drill to remove the rust and then paint it with whatever you can scrounge from the local taggers.

I might just seal it with clear nailpolish and put some red reflictive tape over it. I need more reflective stuff anyways.

Do you have Hammerite paint in the USA. You can apply it to rust, it is very tough and has a good finish. I just patched my old commuter bike for the winter.
Apply wax to the clean frame for a winter coat.

Froze has the best idea. Removing rust entirely is the best option. That also gives the metal a good finish for any primer or repainting and touchups. It will also prevent rust from quickly reforming under the touchups.

Another option is to hit the local auto parts store and pcik up a $4 can of rust ihibitor/primer. Apparently this stuff has a chemical in it that basically stops oxidation and puts a protective layer of clear over it. You'll still have to remove scaling, dirt or surface rust with a wire brush or something, but you won't have to get it to bare metal. Stuff works good. Good luck!
