Here is the finished product with the "Classic" logo #1, Seafoam green over gray:
The back is coated with a peel-off adhesive, easy install.
Honest assessment:
It is a LOT lighter in weight than I had anticipated. We put it on the boat to try, it wanted to blow out. It may weigh a pound if that. Figured it would be denser, heavier, like rubber. That is not the case. You'll definitely need the adhesive. The down side to that is once its down its down.
It is however very attractive, and comes in many color combinations. The size shown is the largest.
Is it worth what they're asking? I guess it is given the custom printing, but that IMHO is the only reason. Now that I see it in person, given the lack of height/weight/cushy etc....if it said "SeaDek" only I wouldn't buy it.
I do feel it would make a nice addition to a swim platform, etc.
