Formica is brittle but is more flexible than one might think. Please take a look at this scrap piece (which is 16" x 4") lying flat:

And here I have it sitting on a 2.5 inch tall piece of metal and I'm forcing it flat down on the table (making the bend around 30 ~ 35 degrees):

And here I am wrapping that same piece around the windshield trim molding (the one with the sharp bend):

As I said if you heat it with a blow dryer it becomes even more pliable. I'm certain there are instructions on the internet about this.
