Walls-Nothing Sticks-no holes allowed

[Walls-Nothing Sticks-no holes allowed]

Interior wall. Washed surfaces completely. 3M adhesive remover removes finish entirely.  Common wall covering. Plastic dots for bump protect don't stick. Tried everything for 2 years.

I can make my own composite materials and polyurethane foams.

Greetings! We have a 2018, Pace Arrow 35 M. The walls are covered with a shiny  covering. The instructions that came with the RV specifically say DO NOT drill holes or screw into walls. I think blind penetrations is bad idea with wiring and plumbing everywhere.

Nothing sticks to the walls. I have tried 3M, Museum putty, nano tape, gaffers tape, every type of adhesive I have ever seen recommend. They all fall off after a couple of hours.

Any secerets not on internet?
