I did more research on this today. I found some interesting stuff. The vinyl wraps would be most beneficial for everything BUT the roof. A 27' class C $2500 ish and you can make all the artwork or design you want.
I found really what I wanted to know after speaking with Rhino. Rhino can be used on 100% of the RV and seal roofs with ease. I saw small dents did not even matter as the liner fills that area in. The only down side is color choice, other rhino lines have tons of colors to choose from. The only other obstacle with rhino is the weight. I am still trying to figure that math problem out.
There are videos on YouTube that show simple concrete block rooms lined on the outside with another company like rhino and it withstood a bomb blast inside the room.
Rhino does not have a lot of locations that apply this product from Rhino but for the same RV listed above it is slightly less.
This might be a game changer for me buying an older 1988 model.
did anyone see the picture in the post? I am still not sure if I am posting the right way.
