My bus has some rust acne, and I used a rust removal wheel on my drill to deal with it. I found nothing but nice shiny metal below the paint. I hit it with rust converter, and am somewhat puzzled as to what to do next as I prep the bus for painting.
This is just above the wheel well, above where one can reach from the outside. Are there two layers of steel, with (for me) a bunch of rust lurking in between?
My guess is that my sanding and rust converter will do a nice job of stopping the rust for a month or a season, but that it will be back. I fear I need to remove the wheel cover from the inside and go wild with a grinder, rust converter, and bondo. Thoughts?
And with the door, would you just fabricate a replacement plate from the front of an oven or some such?
