RV Skylight sealant

[AGC]

I have a 2008 Winnebago View and need to replace the skylight. I looked at the skylight and it looks like there is some sealant on the it to ensure no water gets in the RV.

It doesn't look like silicone, wondering what it can be

x2- pay attention to manufacturers recommendations for that particular piece.

I have a Winnebago View and I think it has a fiberglass roof. The seal around the skylight looks like the seal around the bathroom skylight, bathroom fan, etc.

Is it safe to assume that's its dicor self leveling lap sealant

Thanks all.

Use butyl tape under the skylight and then cover the edge and screws with self-leveling Dicor.

Enernabond.Use Dicor and then Eternabond tape.
