FWIW -the discussion got me to check. I had thought the access panels on my 35-3 were standard laminate but they appear to be fiberglass panels that are very thin - texture and finish on the front but some definite random strands and resin on the unfinished back. That said, they are very much like standard formica/plastic laminate. I would suspect it would make a good substitute excepting that it is probably more brittle than most of the other suggestions so pre-drilling would matter-if you weren't going the straight Velcro route. But it is moisture proof, stiff enough, light enough and available in almost any color. You may also be able to source scraps from your local cabinet shop- The cabinet shop I worked with always had a big scrap selection useful for small projects but not for the countertops they built. May be easier than sourcing a 4x8 sheet of something.
