My bad, not aluminium, definitely rusty sheet metal though and definitely a school bus, an '03 Chevy 6-Window. My question was, can I remove sheet metal and replace it with new sheet metal, or better yet, has anyone ever done this?
The sheet metal is not welded to the frame, but was bolted to perimeter and cross sections below. I just thought it would be easier to replace the sheet metal completely after prepping the frame it sits on. I've looked around and I'm kinda surprised nobody seems to have taken this route. Hope this makes some sense.
And yes, I will fill out my profile
