So I got the new poptop skylight.  Decided on the Bus Depot dual pane one for its insulating ability.I installed it, but I really need a new gasket.  I am sure this discussion has come up before, I just can't find it in the archives.  I want to get the thicker one.  I used that before and was pretty happy with the outcome, but I can't remember which vendor had them.  I ask the list to give me their views on this.
