Wingedryder, you did correctly understand my thoughts. Does anyone know exactly what our wall surfaces are made of so I can research what kind of clear coating might work?

The "Neverwet" product appears to come in two flavors. One that takes two different products and multiple sprays but dries milky white, and the one I linked that dries clear. The former gets nasty reviews on Amazon because of how it discolors the surface. I have not seen any comments on the latter that talks about discoloration, but how long it lasts.

I am looking for a solution like this as I want to use the shower head on the hanger but that will mean the shower curtain will be slightly open there. Even if I use clamps to close it at the seam, I am sure the walls will still get wet. So, to avoid trouble, I am looking for a product to protect the walls from getting wet.
