GMC's just don't look right with a contrasting glovebox and a repro black & chrome dash bezel. You have to mask them & paint. Yes, it is a touchy job, but aren't the results worth it?
Be patient, blue light-stick tape, clean it up before it sets real hard and the trick is: your thumb nail will carefully remove the extra that will get on the protruding thin chrome edges around the gauges...really.
What do you mean I am just playing with my new little digi can?????
