No Koolmat experience but maybe consider using thicker SS. I used .005 SS Shim Stock, 1/8" FiberFrax, 3M Barrier 2000+. No wrinkled tinfoil look like the thinner stuff but some oil canning is to be expected around the areas where you attach items over it. Also a hydraulic punch works great for making nice clean round holes. Ordered everything from McMaster-Carr.
