1988 Royal Industries, Classic - 28' Class C motor home.
First time owner. A newbie to this crazy hobby
Under all windows I have delamination of the fiber glass siding from the substrate.
I removed the washroom window "smallest" to have a look see.
The only sealant around the outer flange of the window was the original stick on black foam tape.
Plus the window opening was cut too big and the window was not centered in the opening.
Leaving very little contact of the foam tape and contoured out skin, mostly at the top.
Water ingress from the top down.
Did or do manufactures put only the foam tape around openings to seal them up?
Or is there an extra layer of butyl putty that is put in.
This is what I will be putting in as I reseal all of the windows.
Is there any method to repair the delamination of the outer fiberglass and substrate?
Thanks to all
Moe
