The cove I have has the plastic ridge that is glued to the foam which slips into the track next to the wall. I will just put some 2 sided tape on the back of the plastic so it sticks to the wall on top of the foam.

Thanks for all the input. It is nice to see a community that has so much knowledge and many ideas. I'll let ya'll know how the installation comes out in a couple of weeks.
