"I believe you are referring to butyl ribbon or tape. "
Thanks for the input but the skylight is not encased in a frame. It is 1/2 smoked lexan
attached to a 1/4 thick seal by adhesive
only, then the seal is attached to the deck
by adhesive only. There is NO hardware
I was just going to use silicone but was informed that it would not hold up. Instead, the old salt
me to use a product similar to 5200...but NOT 5200! Said it was an adhesive made by Dow or Dupont. Unfortunately, this discussion took place on a dock
in passing and in transit. And me without a pen and suffering with old timers. Go figure.
I might just have to go with silicone.
