If you have a local auto bump shop, talk to their painter (or call around). Since my wife had her truck into my local bump shop seven times over the years, I know all those guys on a first name basis.
Their painter did a pair of new unpainted OE Yami hardbags for $250. And it looked as good as any new paint on any new vehicle. He's also done some small cleanup and buff-out work for me better than I could ever hope to do, for very reasonable.
And BTW, black is black. Absent flake or other add-ins, there is only one shade of black. Sure, some paint is better quality than others. But there are not different shades of black. Of course, brand new black may look better than the rest of your 18yo black.
