What Type of Sealant??

[Jimmer]

My 2021 Reflection 315RLTS uses a thick/strong black rubbery but solid/hardened sealant for where some of the wires come into the slides. It's sort of like silicone sealant, but it's much stronger. That stuff is tough.

Can someone tell me what that sealant is? Thanks in advance.

Good question.
The sarcastic person in me wants to say its probably a mix of silicone and unobtanium.

I have used Mono brand black “Silicone Pro” . . . which seems to have very similar characteristics to the original factory caulking . https://dap.ca/products-projects/pro...-silicone-pro/

Thanks, Rob. However, that product appears to be available only in Canada. I guess I'll visit my local Home Depot and see if they have anything close to that.

DAP also makes "Silicone Plus" which appears to have the same attributes, but only comes in clear and white.

Contact the GD parts department, I order my trim sealant from them. They might have the exact one that is on your rig.

Beachcamper 's post reminded me that GDRV had supplied me with a tube of sealant that they use. I still have the tube, and it looks to be the exact same material that is shown in your pictures.

Jimmer It's called Geocel 2300 Vehicle Body Sealant. It comes in clear and black. It states "Specifically formulated for heavy duty truck-trailer, truck body applications, including the RV industries.

Here's a link to the product:

At the top of the page, there is a tool to locate a distributor.

Jim, Thanks so much, that's the info I was looking for. It's the Geocel 2300. I'll order some up use it to seal some things on my Reflection.

Unfortunately, it appears that the entire U.S. is out of black Geocel 2300. Looks like I need to find an alternative. Unfortunately, the DAP Mono black “Silicone Pro” is not sold in the U.S. So, two good suggestions, but just not available in the U.S. Any alternative recommendations would be appreciated.

Open range (Highland ridge) used to use that on their exterior trim in a matching gray color. It is a very robust caulk although I am not sure its the same as the black stuff in the OP. I dont have them in front of me to compare but my recollection says they are similar but not the same. Note that this is free internet opinion and worth precisely what it costs.

Bit late, but I found this stuff to be pretty good at filling and lasting. https://www.lowes.com/pd/Big-Stretch...-Caulk/4411173 I've used it on this and the previous 5er.
