Narrative:

We landed in lubbock, tx. While boarding flight to return to dallas, a very intense thunderstorm moved over field. Began to hail and rain. Hail about 1/2 inch became intense for about 5 mins. When hail stopped I asked a non revenue mechanic to check over aircraft for damage. He and copilot inspected aircraft while I was on phone to dispatch (our books do not require any inspection but I thought it was prudent to do so). Mechanic and first officer reported 'no significant damage to aircraft.' they said they couldn't see the top of wing but leading edges, etc, were all fine. We flew aircraft to dallas. En route I asked mechanic to note his inspection in book for me. He balked and said he could not because he was not really 'on duty.' I was mad and requested follow-up inspection by maintenance on arrival in dallas. Maintenance in dallas found numerous hail dings on upper surfaces, especially trailing edge flaps! (Damage in-flight is on leading edges, damage on ground is always on thin upper surfaces.) we wrote up damage and changed aircraft in dallas to continue trip. I felt I had been operating a safe aircraft and was not aware of any damage to aircraft prior to or during flight. (I had tried to make sure in fact that there was no damage, but mechanic had not inspected properly.)
