I am planning to install Formica-plastic laminate on the wall between the counter-top and wall cabinets. On custom kitchens made a few years back, I have seen small metal strips that cover the bare edge of Formica that would be exposed on an end wall, and also help with the joints on inside corners. I have not been able to find a source for these strips. I have the Formica and i'm almost ready to go. Help !
