Hardening the Dash for a wooden veneer; how should i do it? Lots of Mahogany Flash

[darkone]

so, im trimming out the interior of the 70 chev stepside with mahogany to match the custom bed. I need to figure out a way to harden the dash pad for application of a veneer so that if it is bumped, hit, or kicked (hope not!) it wont crack.
I must use an unfinished mahogany veneer because i have to be able to match the stains on all wood accents, of which there will be a lot!
