How to treat large dings that have rusted?

[Jeffrey]

I have several large abrasions through the paint that have rusted. what do you do to treat them? If I just paint/fingernail polish them will that stop the rust underneath, or do I need to remove the rust first? If so, how?

Thanks,

Jeff

Clean the rust with fine steel wool, then enamel.

Jim, can you elaborate on what you mean by "enamel"? Thanks.

I am not Jim, but hobby shops and the fingernail polish section of drugstores, etc. have many colors, some of which may match. Don't try to touch up all in one go. Layers, light sanding. Be happy with beausage. We live in Rivendell, remember. Use a pencil eraser to apply pressure to a little wad of steel wool and keep the abrasion to a tiny area. Twirl the abrasive. After touch up, you can even get and apply clear fingernail polish. Fear not. But leave no rust under paint.

If the areas are pretty large, it might be worthwhile to first apply masking tape around the area, do a good sanding down to the metal with automotive sandpaper.  Then apply a rust-inhibiting primer like Rustoleum, either by brush or spray.  If by spray, of course you'll want to re-mask and cover the rest of the frame with paper or plastic to prevent overspray.  Then you can do final coats of color in a compatible enamel.  If you have a good color match, you can try to blend with the original paint by tapering the spray off at the edges, and (after a good long time to harden the paint), feathering the edges with very fine sandpaper.  Hard to explain, but I've done it on a car body.  Important:  first test the compatibility of any paint that you use on an inconspicuous part of the frame.  Some paints will dissolve others, etc.  Hope this helps.
