Steel wheels on wifes prius c

I had the wheels off in October and went to rotate the tires today oh what a surprise they were rusted on to the point it took about a half an hour with a two by four and a 5 lb hammer to get them off. I put some no seize on the center wheel hubs hope that stops this crazy crap. I know it was a salty winter here in Michigan but didn't think they would be like that . Just thought I would pass it along so if anybody else live in the salt states may want to pull your wheels, better in the drive way then if you get a flat on the road.
