Copper Spray on Headgasket - Yay or Nay

the point of spraying the individual sides of the MULTI layer metal gasket - is that that particular side adheres to the surface its mated to.
The multi layers - then allow the two to expand and shift at their own pace sliding on one another. While keeping those two surfaces - sealed to the head/block.
This is why you ONLY spray the two sides - NOTHING in the middle.
And this is why you do NOT spray a composite. This would cause the composite to not be able to shift/slide with the different expansion ratios - and it would inherently pull the hg apart.
