Door scrape on sidewalk - touch-up tips?

[slotmeister]

Aaargh! Had my door check-straps replaced some months ago, but thoughtless/brainless passenger has just let it go and strafed the sidewalk with the lower edge of the door. Paint is Diamond Blue. Am I advised to touch it up immediately to prevent surface rust? Area isn't visible, should I go looking for genuine Diamond Blue touch up, or is it actually better to use some kind of sealant or something?

To answer my own (and possibly someone else's) question: I did some research after I calmed down, found mention ofa product called Zinga, which seems to be a brush-on zinc coating. I intend to dab some of that onto any exposed metal before using the touch-up paint.

Another idea is to take the same passenger out for a drive every six months so when they open the door it scrapes the rust off leaving it nice shinny metal.

Diamond blue ain't cheap paint. If it isn't visible just make sure it won't rust.
