Help With Roof Rust and Wood Rot
Hello, severely unskilled and unknowledgable here.
After watching many videos and searching for hours, we haven't found someone with our exact scenario. Our shuttle bus is a 2008 E350 v8 finished by starcraft I believe. When we removed our ceiling panels we were surprised and pleased to see structural ribs supporting the fiberglass roof! But now we have an issue where a leak has been present long enough to cause rust on the ribs and rot on the thin pieces of wood sandwiched between.
From my novice level of skills I see the only way to truly solve the issue is by removing the entire fiberglass roof and doing the necessary repairs and replacements.
In my skill level, workspace, and time frame, I am leaning toward cleaning up what rust I can and painting over it all heavy (post leak repair).
Curious for any advice on this.
