I have noticed this with many jobs I do and soon realized it is not product specific. I found a way to eliminate this almost completely on most of the vehicles I do. In my shop I have a large Air Compressor that is lagged to the ground. I made up a long single wire cable with a metal alligator clip on each end. I clip one side to the lag on the compressor, and the other to the body on the car. Viola, car is grounded, no more static! All for about $10.
