JBL grey paint for horn touchup?

[Harkness]

both my 2397's have a few chips in the paint on the front edge from being stored vertically on the mouth. it would be nice to touch them up. i don't want to refinish them entirely..

is the correct grey colour paint something that is available?

[grumpy]

I hope someone can help you and that the touch-up areas are small.

Gray can be a very difficult color to match (especially if viewed
in different lighting conditions). ... used to have equipment racks
painted per a very specific spec. When California decided to not
allow it to be sprayed anymore, we had a very difficult time getting
a reasonable approximation using a different formulation.

Good luck!
