    Black sealant

    Anyone know what that black sealant they are using to seal up some areas is. I have in on the underbelly and sealing the electrical wires headed into the generator compartment.

    No, but I wondered the same thing. Wouldn't mind getting a tube of it if it's available.

    Thanks much. Didn't realize it's the same as the stuff used on water features. Nice.

    No it’s not the foam. It’s definitely some sort of sealant.

    I found something pretty close to it at Home depot. It is polyurethane based, sold for sealing roofs. The main difference seems to be it is more of a flat black, than the gloss black in the pic. It worked well and IIRC was about 6.00 a tube

    I had to pry some apart and it's really like a foam sealant. It's sticky but also has a "foam" like element to it - at least on my 2022.

    Watching as I have the same question. I see this used under the slides where cables pass through also in the 2way fridge (back panel) to seal the compartment at the bottom. I have heard it is polyurethane based and is used on motor homes since it is so durable. The material is very rubbery and soft but yet, cured.

    I wonder if this is it? https://www.dyersonline.com/sikaflex...-adhesive.html

    No, I think JKWilson is correct in the link he shared for boring-smith expanding foam sealant.

    Black sealant

    The OP indicates in post #5 it is not foam-based sealant (like what is used to seal holes/gaps in the underbelly).

    The picture posted in #5 does not appear to be foam based.

    You have my curiosity now. A tube of it is in my amazon cart.
