Best material for bulkhead surface?

[catman115]

Rockdoc..there are pictures of my seafari cockpit under the heading of "wiring diagram" in this section posted be csick nick. I cleaned up my bulkhead and picked up a 4 x 8 sheet of a .125" thick material used for bath or shower enclosures at my local home depot. I got the pebble surface because I thought the smooth would reflect too much. I made a cardboard template of the walls and cut the panel and applied with a good marine adhesive. it worked fine for me...just an idea for you
