Re: Leaking Rain Through the Walls
After my experience with the roof caulking (check my thread) I'd use roof caulking on the inside and paintable caulking on the outside to leave a cleaner, more paintable surface on the outside. Just my thought. Oh yeah, before caulking be sure there is no corrosion or rust on the panels. Use a rustproofing primer if you need to remove rust and start at the bare metal.
