If your new skylight is polycarbonate (Lexan?) do not use Dicor. There is a different caulk that is recommended, but I can't remember the name.
I did some searches regarding polycarbonate skylight sealants and found mention of Surebond SB140 Skylight sealant... here's a link:SB-140. SB-140 specs state it is compatable with rubber - like my EPDM roof. So this is the correct sealant.... Right?
Yes, that is the one. The company I bought my new skylight from included a tube with the skylight. I used butyl tape to seal the skylight to the roof and then caulked with the SB-140.
