I think I am starting to figure out why this bus was cheap, moister whereever I look and of course the rust to go with it.
Tried to remove the sidepanels under the windows today to see how it looks. Found moister and rust underneath. Which means I will be removing all of them and try to do something to prevent it from happening again.
What is the easiest way to remove these panels? Do the windows have to come out to get them out? Or should a guy just cut them off at the top?
How in the world can I properly seal the windows that no more water enters the seams?
of course I took pictures

how do I get the top of the panel out, does it fold around to the outside and is screwed there again?
