It appears that I have to replace my skylight seal.  After only a couple or 3 years, it has developed a break in the seal right in the middle rear.  It also seems to be "deflated" along the rear edge.  I checked the vendors, and found prices vary quite a bit.  Not a lot of info about them, although Bus Depot claims that theirs has a metal strip so no glue needed.  Any consensus on which one is the best.  They are all pretty inexpensive, but I hate to keep replacing anything.
