Front Cap Leak

[JGallagher]

Good evening,
I believe that I have found the source of a leak on my front cap of my 2017 E-450 Chateau.

When raining, water runs down the front of the cap and then enters thru the molding strip on the cap that is just above the windshield and gets wicked up by the boards on the inside.

I would normally just seal with some silicone but I have seen a few posts that state not to use it.

I do not know why that is the case so I am looking for suggestions for a clear sealer to use.


Thank you.

I have been replacing all of my body and moulding joints with Lexell clear sealant.
Will never need to do it again.
Tricky to learn but youtube has a few of vids to show how.
Turns out very nice.

Hi Jimmers,
I just watched a couple of quick videos about Lexel but did not see any particular instructions about usage.
Would you kindly elaborate about your comment? What's the tricky part?
Thank you.

You prep as you would same as silicone.
Mineral spirits to strip out old and alcahol to prep for new.
Apply the Lexell and imediatly spray with foaming window cleaner.
Dip or spray your finger in mineral spirits and press along the sealant joint as you would with any sealer. Only once.
Lexell sets up very quickly and you usually do not get a second chance.
It sets up fast.
Gives a crystal clear seal that is an adhesive as well as water tight sealer.

Hello! I'm not sure about sealants nor did I have leaks that I'm aware of. Nonetheless, I bought a class A this Aug and realized the front caps was separating from the body of the coach, it appeared screws had rusted. I took it in and they fixed it by replacing the screws.
