Touch up paint for Preamplifier ?

Does anybody have a suggestion for a paint color (and source) that comes close to the color of the stock metal that almost every black Amplifier and Preamplifier case is made out of in the 1908s-today ?

I’m looking at creating a custom stainless steel "open cover" for my tube preamp that will provide more ventilation and would like to paint it in a color that would closely match the rest of the OEM case.

Unfortunately, I can’t really make the open cover out of the stock metal used in most preamp/amp cases so it is going to have to be painted to match.

I’m hoping that some company makes a paint that would be used to cosmetically touch up preamp/amps that have been scratched or damaged.... but so far I’ve struck out in finding something like that.

It happens to be a BAT preamp, but the same metal used in the BAT preamp case appears to be very similar to metal used Mcintosh, Denon, Marantz, Yahama, and almost every other brand.

Any suggestions would be most appreciated !


Satin or semigloss spray paint. Spray in small container and let it set up to get thick then use a very small brush to touch up.

Take the existing cover to any paint store and they can computer match the color.

Tonality near a limit, ie, pure red, blue, or green, or CMYK.

Anything that is close to the limit of being a pure tone, or, conversely... whitish with a hair of the given pure tone.

Those are the hardest for any paint matching/measuring system to match up to.

You are dealing with not a black but a close analog. Which means it might not come out as perfect as you want or expect it to.
