upholstery backing and materials

[chris mc bride]

Working on doing upholstery in my panel. Want a professional job done right,but doing it myself. Lots of fabrication experience.

What is best for the backer board for doing the rear walls and roof? Also if have done what did you use for upholstery?Lokking at about half a dozen types. Already have boith lined with reflective insulation.

I have wiring and provisions for running more if needed. Have speakers and lighting. Also have an amp box installed. Just need to put up the backer and decide on the exact material. I know colors or think I do.LOL

Tips and hints are welcomed.
