I had the same issue Tommy.....
When I called and asked about it - they sent me a spray can of Rustoleum High Temp, Flat Black Paint....I was not impressed.
But - because the Rec Tecs of this series are powder coated, I know that "paint" does not stick to powder coating ( even if it was the same color...
...) and I think that they do not really have an answer for us on this.
In balance - part of the price of a Rec Tec is that it
is only powder coated steel... and not 304 grade stainless.
A considerable cost difference to manufacture......
