Hi everyone. Someone has perhaps already asked this question, but I didn't find it yet.... we are restoring our 1963 Bambi (hubby is Nor-Cal Bambi) we have the new laminate on our new countertop

~ it is the edging and moulding I am not sure about. We have found some vintage looking aluminum that will fit on the counter edge... but what about between the wall and countertop? Sort of a little backsplash... the plastic (?) material that was there is too hard and icky to use again. What have any of you used? Where did you find it? Our local hardware stores and Lowe's haven't had anything to solve the problem. The material needs to be able to fit the contour of the back of the Bambi where the kitchen is located (curb side).
Appreciate any reply to help enlighten us! Thanks.
