Good evening all I am hoping you can help me! My husband has been digging around in his parents attic and found his mighty metro racing set from 30+ years ago. By some miracle it still works although patchy in places. I have a few questions, can you use anything on the track to make the cars run smoother I.e wd40? What cars of the new generation will run on it as I would love to get him some new ones for his 40th birthday for him and our kids to enjoy. The track is 12V so I'm guessing the looney toons cars won't run??? Any help with thus is greatly appreciated. Chloe
