Side note. Something I just thought of:
A buddy used gray interior vinyl and fabric paint on his titanium fox interior which he bought off the shelf at “advanced auto” (a chain auto part store here in NY that you may have also but any auto part shop prob has it). The brand name was DupliColor. It is a damn good match and it’s Half the price of SEM paint. We sprayed the SEM/DupliColor next to one another on a piece of plastic and they were a 99% match. Couldn’t really tell the difference and one didn’t look better than the other. They were both perfect and the DupliColor was just a regular gray (not specific titanium gray) off the shelf at the local auto supply shop. Therefore, that’s always an option for you also. Again, as long as everything is painted then it all blends nicely and looks perfect instead of several different shades. Even if they are very very slightly different shades, they will still stand out. Do the entire interior.
I will find out the exact name of the gray he used because I’m sure there are several shades available. It looked really nice! The picture attached may not be the same color, I’m just sending you this to see the name brand and what the cans look like but it’s not necessarily the correct gray. I will find that out later.
