Also,thin masonite or aluminum sheet can be flexed around and attached to a 'shaped' handle,and then 3M self-stick sandpaper attached to the face of the masonite or alum..

Neil,
I've made foam shapes with the same convex shape, and glued sand paper to maintain that shape.
If you want to flatten the convex shape, then glue sandpaper to a flat board and use that.
