New steel frame, paint issue -- options? I've bought a new chromoly tourer.  It's a very nice bike but I noticed (while on a rather wet ride the other day) a loose flake of paint that fell off when I touched it.  It's on a rack-mounting lug, can only be a fault in the original paint job, and appears to be down to bare metal.

It seems to me that this is a weak spot for rust to set in, and should be sorted out by the manufacturer or dealer.  Would touching it in be as robust as a factory finish if they could come up with some touch-up paint?

It seems silly to treat something that should be easily fixed as a warranty issue, but I don't want a spot that's going to let rust in.  Am I overthinking this?
I'd have been happy with a repair, even doing the work myself, but neither I nor the bike shop could get suitable paint out of the manufacturer. 

It ended up being a warranty replacement. The shop (a major chain of bike specialists) were good; their options were limited.
