Expert Reply:
Hi Ashley, yes! Dicor Self-Leveling Lap Sealant # DC94SR is a great choice for sealing around a replacement RV skylight. Install the skylight over butyl tape # DC38SR first, then apply the Dicor over the screw heads and around the outside flange to help keep water out. Skylights take a lot of direct sunlight, so I also recommend checking the sealant during your annual roof inspection.
