Type Sealant at gutter rail on 2021 Montana

Does anyone know what type of sealant they use at the gutter rail where it meets the roofline on a 2021 Montana. It’s white. I’m not sure it’s dicor ? Maybe its dicor non self leveling. i have a spot that already needs touching up where i can see a penetration point. I assume its regular white color for the montana's?

Is it okay to use Pro Flex RV in this application as well?

Mark, someone on the Montana owners forum says ivory is a better color. I swear mine has proflex on the edge on most of it but where i had a repair under warranty made it is now dicor.

The color doesn't matter to me as it's in a location not easily seen from the ground. I just want to make sure I use the correct stuff so it will seal well and last.

If the sealant is going to be in contact with the TPO roof membrane (and it looks like it is) I'd use DICOR non leveling "lo voc" or Alpha-Systems 1010 non-sag, in beige or almond.

Keystone used silicon on our 2011 Cougar HC. About to peel it off & replace.
Remember not to use any petroleum based cleaner on the rubber roof membrane.
