Touch up paint?
 

My panasonic has some rust on the top-tube cable guides. I can get the rust off but I'd like some tips on selecting the right paint. This will likely be applied by brush to small, localized areas.

What type/brand paint should I use?

I've used Testors model paint and just mixed a close approximation of my bike's paint. Works well.

The other thing you might want to consider is using a rust-preventative primer first.

How are you removing the rust? I've got a similar situation with a few small rust spots--not large enough that I want to get out the sand paper, but enough that I want them to go away. Any luck with rust converter?

I was thinking of using the brass wire wheel on my dremel and using some naval jelly for what's left. it's kind of an intricate little guide so i doubt i could hand sand it. i'll likely use some rust-inhibiting primer sprayed on. any recommendations on that?

nice thought on the testors! i haven't used that stuff since i was a kid and my dad and i used to "repaint" my bashed up hot wheels. great stuff.

Nail polish also works well. I've used Testors too; no problems with either one.

1+ Testors and rust removal with an emory board or a dremel with the appropriate bit. Lp

I'm a big fan of the ZIG Painty Markers. They are available in a variety of tip sizes and come in 60+ colors. Maybe not a perfect match, but easy to apply.

I'm not really familiar with bike finishes but I am with mid 80's car finishes. Is there a clear coat on top? I know I can find clear-coat testors if I need to.

Where does one find Testor's paints? This reminds me - I'll be close to a Macy's today. I should skip in and check the fingernail-polish.

any hobby store should have Testors. Or Walmart near the toys.

If you are looking for an exact match and don't mind going for a few $$, most modern auto body shops can match paint colors almost to perfection.
They may be able to mix a small quantity.

going that route would likely be more than I want to spend. I just need something to last for a bit (at least a season or two) until i decide if I want to strip it down and start from bare metal.
