Freeing up the roof fan rubber seal

[rustyjax]

What's the trick to freeing up a stuck roof vent? Without tearing up the rubber seals, what tricks do you have to separate them! FLORIDA SUMMER SUN is HELL on these!

Can you get up on the roof with some Silicone spray to lube up the rubber seal? Use the little red tube to reach up under the cover.

Try to clean all the surfaces with alcohol before spraying on the silicone. Some use Aerospace 303 instead of silicone. I've used both at different times.

Just going by my models, but taking the inside screens off would allow lubricating spray from the inside.
