Can rust on a bus be repaired?
Yes, it can. But its not an easy task. A lot bus busses get rust in the battery tray, the floors and the rockers. Busses used in very salty areas also get bad frame rust. In rainy areas, rust under the windshield frame is common. The proper way to fix any kind of serious rust is to cut the area out and section in either new pieces or pieces cut from a donor bus. Anything more than light surface rust will probably need to be sectioned. If there are any holes, then sectioning is your only option. Sure, you can fiberglass the holes over, etc, but how long will it last? I have fiberglassed very small holes in floors, where it won’t be seen, with good results, but I don’t recommend it for body panels, and definitely not for structural components.
