Sticking Fantastic covers
Glad to know that I am not alone in my small problems.
My Fantastic Fan covers tend to stick, also. When the trailer has sat for a while, I try to remember to pull out the knobs and break the seal manually before turning the fans on for the first time.
I suspect that a good application of silicone to the seals will alleviate the stiocking problem. Silicone does a good job on sticking window seals. This is on my agenda when I next have an opportunity to get on the roof. Since my trailer is in a storage yeard, I have to transport a ladder out ther.
Like gsalmon, I have some flourescent covers that routinely fall off and some that do not. I can't see a physical difference in the plastic or the fixtures.
