thick vinyl molding insert

I don"t know if any one else has used this but I ran across this on ebay. It is 3/4 inch thick vinyl molding insert. It is channeled to attach on the outside and not like the thin stuff that you have to bend into the molding channel. It works very easy. I made sure I sealed all the screw heads with some kool seal flexible byutl tape before I installed it.What I liked most is that it covers up the channel and you don't see the edges. Only time will tell if it is any better.Sorry if pictures are too big still have not figured out how to make them smaller.
