Ty,
All GM trucks are base coat / clear coat since the body redesign in 1988 .
PPG can most likely mix the gold in a single stage DCC product , but BC/CC in DBU will be alot easier,
just make sure you cross hatch across the hood , roof , and bed floor as it has a tendenacy to tiger stripe if you keep going one direction on all 3-4 coats . The base will dry to a simi flat look , mixes 1:1 with DRR reactive reducer and the clear give the color POP and UV protection .

Make sure you clear over the DBU base no later then 30 minutes to an hour after spraying it , its a wet on wet porduct. I have been spraying it since it came out in 1987/88 , and never have had any problems with it .
If you let the base dry to long , the clear has nothing to bite to , and could cause a delamination of the clear.

If you have mastered good gun technique with Kandys , then you shouldnt have much problem with PPG's DBU , now DBC is a tad harder because its a non catylized base , unlike DBU . Its why I stick with spraying DBU , because in a heat make up down draft booth , you can pound the living crap out of it and have no problems !!!
Need to in a production dealership . Its what makes me alot of money !!
