I purchased a new CroMo steel frame, MTB style and have been riding it for about a year. It's already had the paint chipped off in a few places due to accidents / clumsiness (the LBS guy has chipped the paint 3 times - each with a "Whoops!" and a quick apology - he's never ridden steel as its quite rare here in Taiwan, so I sense it may just be a lack of understanding there).
Anyway, I usually put some clear nail polish over the spots and keep riding. Not sure how long it lasts. Is there anything else recommended? I've seen a little bit of rust in the mid-fork braze-ons after removing a front hub, and I used some frame saver spray there. Many of the exterior nuts and bolts have rusted somewhat, but I know these are replaceable. Is there any way to prevent rust on places like those (for instance, the rear rack mounting screws are looking pretty shoddy) or should I just replace them continuously.
Am I worrying to much? I want this frame to last, as well as the parts, but I don't want to get so involved in care that I can't ride it in piece of mind. How much rust would it honestly take to put this frame in bad shape?
