Walls in an '81 Excella?
Hi all - I have been reading tons about stripping walls down to the original aluminum and I am willing to tackle this project, but I honestly cannot see that I actually have aluminum under all the coats of paint on my interior. The ceiling looks original - beige vinyl and very sticky to the touch, and the walls have been spray painted by previous owner twice. Nice finish but a terrible color combo if two-tone blue. Does anyone know if I could have a different type of wall under there or is it definitely always aluminum?
