Rust on top of cab
Hi all. I have recently bought a 2004 Forest River Lexington Class C/B+ motorhome and am in the process of completing various repairs. I removed the grungy looking sealant across the seam where the cab roof meets the fiberglass RV over cab section. The sealant had failed (looked like white bathroom caulk) and the metal behind has started to rust. This must be fairly common. Anyone have a recommendation for what I can brush in to hopefully stifle the rust before I apply new sealant?
