Frame paint (black)

[The Foolish Fellow]

Any recommendations on a black frame paint that would blend in with the original

Some have used Hammerite in the past.

I've used Hammerite on bike frames only for it chip quite badly. Even with their special primer, its not as tough as the reputation suggests.

Action Can ZG-90 looks pretty good but the rusty areas had to be cleaned back to bare metal. It's zinc rich but a zinc passivate etch primer would be better.
