Starboard like material
 

Looking for Poly-plastic material that is cheaper than Starboard/King Board that is used for making backs for seats and replacing the heavy plywood on hatch cover.

I beleive Cuda had used something that was a product that was cheaper grade than Starboard and did not have as nice of look, but thats what I want. It gets covered with upholstery anyway.

Looking for something cheap and lightweight.

Answered my own question when I relized I should try and search this forum under "Starboard".

PVC board.
