Running board mats

[Brace Bailey]

I just in-wrapped my roll of Vintaque running board material - and discovered that there are two mats already cut. They may be 1/8” too big, but I’m going to leave them out to see if they shrink. Right now they will almost lay flat on the boards.

Now the question is: what kind of adhesive can I use that will let me slide the mats under the zink edges? If I use contact cement, I’m sure I won’t be able to slide them under the edge. Any ideas?
