moth-balls repell many unwanted varmints. I've never heard of them being used to repell cats, but a few in the garage may be worth a try. use enough to make your garage smell like grand-ma's closet.
very dangerous for cats to be in the garage anyway. since radiator coolant tastes sweet & animals enjoy drinking it, a small puddle on the garage floor could mean toxic death for the kitties, and it would be your wife's fault for letting them in.
