the following is pure conjecture on my part. i noticed the alpha shipped with the skylight is high solids, low VOC. maybe the equivalent of the non-sag dicor but with different VOCs possibly. Ive seen the plastic on the skylight discolor and be prone to cracking right where the dicor stops and the skylight begins on the sealing edge. at least the non-sag might be a better choice here with less least on the edge next to the acrylic.

I wonder just how much of the deterioration of the skylight is purely related to the elements and/or mounting stress points. My roof is on a fifth wheel kept at a seasonal site in Florida, full sun and salt air, 24/7. The majority of our neighbors, who have developed leaks, get them from the skylights. Most if not all of the skylights are black, attract sun and get very hot, every day. To me it makes sense that it is just a matter of time before they get brittle and start to leak. Shortly after caulking, I spray painted mine with an entire can of Krylon, 4 coats. It is now bouncing the sunís rays and is much coolerÖ
I am also curious to know if the skylights are made of the same materials. When cleaning this one I was surprised that when I pushed down on it, my thumb easily depressed the surface, very similar to a large childrenís ball. Could have sworn that the material on my past RV skylights was much harder.

your pretty much right about the sun. i just snug them down when i swap them. too much deformation when tightening will crack it over time. 303 at regular intervals might be better than the VOCs in paint but ive never painted to know. if i can find a skylight with the crazing at the edge where the caulk meets ill post..

X3 on the Eternabond tape. It fixed my leaking problems around the antennae, bathroom skylight, and the front part of the roof (above the front bunk) where it starts to make the curve. I had major leaking problems above the front bunk and this fixed it. After 2 years it is still holding up in the Texas sun. Very easy to install and is not messy. I've used Eternabond brand and another cheaper version found on Amazon and both work and held up the same.

So the title to this thread included other seams so would love to ask if anyone caulks around the windows as well as the roof. We have Microlite 21FBRS & DH finished roof today & was wondering .....

i do windows all the time. some have a foam sealant that dries out leaving large gaps, especially on the non-smooth side coaches. my fav is lexel at ace in clear. the 35 year silicone/ acrylic is common for colors.

What are the frameless windows sealed to the unit with, looks like a gasket of some sort.
