If using wooden skewers, soak in water for 30 minutes.
Combine the San-J Asian BBQ Sauce and melted butter and pour into a large food storage bag. Add the shrimp, close the bag, and flip several times to coat the shrimp. Marinate in the refrigerator for 10 minutes.
Thread 2-3 shrimp on each skewer. Discard any remaining marinade.
Heat grill to medium-high, brush the grill grates with oil, and grill the skewers for 2 minutes per side.
