thanksWe used to use the molding but not any more. It looks nice for a while but it's hard to glue on and make it stay. If you can cut the material so the channels are on the sides, not on the bottom, it looks better. Dibond looks the best because of its solid core.
We use an aluminum channel ( from Outwater Plastics I think). It can be left as is, painted or covered with vinyl. Attache with lexel similar and a couple screws on each side, just to be sure.
