Just an idea - Gerry (ger21) showed a set of mdf panels routed into a wave design - might be do-able as a design - and it would look "high end" -- but still have classic resale value too!
Consider making it as an open mold and just using fiberglass and (vinylester) resin? Would have the wave --but not buried in the "bar top" resin.
Cheers - Jim
PS looking forward to some pics when done -or in progress
