Wheels: If you have steel wheels, you may also have rust. I would recommend sandblasting as the easiest way to remove the rust and prepare the base metal for refinishing. If you are going to use a hubcap over the steel wheel and do not care about the looks, and encapsulator will work just fine.
Condominium or apartment complexes, which are also considered multifamily homes, come in various shapes and sizes. It may be difficult to tell that such a building is a multifamily home by just looking at the exterior. These structures can have one central front door and resemble a very large single-family home.
An example of a multi-family home would be a duplex, which is a house that is divided into two homes. One family could be living in the upstairs part, with another taking the lower level. Both levels have the necessary aspects of a home such as a kitchen, bathroom, bedrooms, etc and have its own main entrance.
