I suspect that the owner will start to suffer too if you use silicones on his track. They definitely leave a residue that spoils traction for other types.

There are some of us who think they are the work of the devil and should never be allowed on a slot car track. They just don't mix with other types.

Ditch them would be my advice but then, if all your cars have them, it might get expensive unless you just keep a few that you can race at the club.

I would try to persuade them to ditch anything but plain rubber or urethane, don't use anything that leaves the track less than pristine - apart from rubbering in of course.
