Suggestions for painting letters on dash knobs?

A couple of my dashboard knobs have lost the white in the letters. Any suggestions for best way to restore these? Type of paint to use? Technique to make it clean?

I like to dig out the old paint with a dental pick and clean it well with Dawn. I them use a paint prep solution and paint with Testors model paint using a very fine paint brush. I find everything I need at Hobby Lobby in the model section.

I just did some, used Testors model paint, infilled the letters and let dry for a day. Then I took a rag and paint thinner and cleaned the little bit that got outside the countersunk lettering. Looks perfect. Prior to that I put the knobs on the buffing wheel with a little Mothers

Great - thanks for the tips. I'm off to Hobby Lobby!

I did kind of the same thing but used fine cutting - polishing compound on a thin rag wrapped around a paint stick and buffed till only the the letters or numbers on the shift knob had paint.
and it makes the knobs look new!

Paint with auto touch up paint...slightly off white. Sand entire knob with fine grit paper until no white shows on the flat surfaces...then spray with clear coat.

Update: swung by an art store for paint and a brush since they were closest to me. Found a paint pen which fits the grooves perfectly - as if it was made for it. Only thing is the color is WHITE as opposed to an off-white or bone white which I think would look more natural. Cost me something like $3 and change. It's called DecoColor Opaque White Paint Marker with Extra Fine tip. Will not fit the grooves on the shifter knob - too thick for that but like I said, perfect fit for the dashboard knobs.
