Rust in the Threaded fender mounts on a Steel Bike?

Hi,

I have noticed that the only exterior spots not painted on my steel-framed Lemond are the threaded holes by the rear drop-outs (for fenders?). Being threaded they hold water and start to rust almost immediately; get caught in one shower and the problem has started. I initially squirted in a bit of grease, but that doesn't look so great, so it's probably better to put some paint in the hole, or even fill it with epoxy, granted I have to get the grease out first (maybe with a Q-tip and citrus cleaner).

I want to do something about it before the rust gets going and moves under the paint.

What are some solutions that other people have used for this problem?

Find a short bolt that fits the threads and wrap it with some teflon pipe sealing tape. The tape will keep the water out and keep the screw from vibrating out.

the tape may also keep water in if any gets past it.
my first recommendation would be to dry it out with a q-tip, clean out the rust as best you can, and then cover one side with masking tape, turn that side down, and then spray some frame saver into the hole and let it sit, harden and dry. then remove the masking tape.

Don't forget to grease the bolt.

Dry it out and apply some wax over the threads.
If you want a keeper, try a nylon M5 bolt (or machine screw), these are cheap, light and rustproof but dont try fixing things with them.
