Hi Blair,
I resprayed my 6MDM apron, put a Pinball Rescue decal on it, and it looks great. Lee's stuff is excellent.
Did the game you purchased come with the apron? You could do the same, if the condition of the original apron is not to your liking.
If you do need an apron, then the apron I have for sale could be used for your 6MDM. It's the same shape, you would need to sand back, prime, paint, finished with decal. Let me know if you are interested in the apron - it's originally from a Bally Hang Glider. It's sitting here doing nothing, so anyone who needs one, let me know.
