What caulk for fiberglass seams

[ParrishCamper]

We just purchased 2016 Eagle TT. The color is cream.
I would like to caulk a couple of outside seams on fiberglass. The manufacturer used clear caulk. Dealership said to use silicone which I thought was a no no.
Only clear caulk I have found is Pro Flex Rv Crystal 28100V Geocel.
So I thought I would ask here.

Geocel Proflex is all I'll use. VERY good stuff. Just have to smooth it with finger dipped in mineral spirits or dawn / water opposed to just water. It sets up FAST, so only do short sections at a time. You'll be hard pressed to find a sealer better than Geocel.
