More FYI, I went to a local full-range Formica / Wilsonart dealer to look at swatches of laminate in so-called "Stainless Steel" finishes (there are many options).
All were, to my eye, a poor substitute for the 'real thing', and though certainly less expensive and would lend to easy installation in this application I wouldn't have any of them myself because it would look so 'cheesy' next to things like the OE SS range hood. YMMV.
But, there are many nice laminate patterns other than SS if interested in that, and it is a good material for the application, IMO. You don't need to 'bond' the laminate to the fridge, just slip it in the provided slot.
