Since I would guess a large percentage of the people there would have a complete kit, you could focus a lot on the upgrading & upkeep aspect:
Basic fiberglass maintenance/repair
Cleaning techniques/products
Paint care (or maybe that's what you meant by paint tech)
Suspension tuning/setup - alignments, camber/toe-in/caster, adjustable springs, 4 link & adjustable a-arm, etc.
Proper etiquette while waiting at the next stoplight for a ricer (or vette) to catch up....
