The question is: is running NM on the surface of GWB in a garage compliant with the NEC? The answer is, IMHO, yes, so long as it is not subject to abuse, and it is secured using the longer staples through the sheetrock and into the joists or studs. While there are many among us that think this is not the best choice, because of looks, durability and the like, it does meet the code.
