place wings onto grill in organized rows, close cover to cook for 5 minutes
open grill and check progress of the cook.
if the skin on the grilling side has started to crisp or blister, flip them over and exchange their location on the grill with the slower cooking wings and close grill for another 2 or 3 minutes
once all wings have been flipped over, repeat the process outlined earlier, until they are all just starting to crisp and blister on the outside as uniformly as possible
brush the sauce onto the top of the chicken lightly, close grill to allow it to cook and "lacquer" .
after another 5 minutes, and the sauce has formed a glazed appearance, flip them over, once again moving them around from hot spots to cooler ones in order to facilitate even cooking
apply sauce again, repeat the "lacquering" process.
flip them for a third time. you will start to see charred spots on the skin, and especially on the tips
baste with sauce once again, much thicker this time, paying special attention to cover the charred bits
close the grill again for 2 to 3 minutes
