Re: Rust underneath
Tango's advise with the pressure washer will also have one more added bonus.
Many of the buses if you look underneath, will have a white powder forming in some spots. This is caused by two things.
Salt that has not been washed away, and the venting from a flooded acid starting battery. Both mine had this around wheel wells, and over the battery box.
The pressure washing you give it will wash this all away. Just be sure to let it dry for a day or so in the heat, before applying the rust stop spray.
For the rust stop spray, I like to use a clean new hand pump weed sprayer. They also work good for spraying degreaser, ect.
