This color was used on many factory GM models from 2015 to 2017.  Depending on the model and year it was used this color was called Overcast, Light Steel Gray, Gray Silk, Slate Gray.  There are known variations in the color from the factory so this paint will not match all vehicles stamped WA-402Y.  We recommend it for overall painting only.
