My driver-side bed window in my Travato leaked again. Same spot I’ve fixed before.
Last time I used DAP all-purpose silicone, and it held for a while. This time I had Flex Glue handy, so that’s what I used.
This is the repeat fix, step by step.
What I used
- Flex Glue (clear, 2.8 oz): https://link.amazon/B05NrznHC
- Paper towels and wet wipes, to clean the seal
- A towel under the window, for the overnight rain check
- A tire plug from my ZERINT TT-M26 Tubeless Tire Repair Kit, to unclog the Flex Glue cap: https://link.amazon/B0dqlZXn9

The fix
1. Clean the whole seal. I cleaned the whole window seal area with paper towels and wet wipes. A clean seal matters more than rushing the glue on.

2. Apply Flex Glue along the leak. I ran Flex Glue along the window seal where it was leaking, then cleaned up the mess around the area and left it overnight.


3. Overnight rain check. I left a towel under the window and let my van sit in the rain overnight. The next morning there was just a bit of damp on the towel — way less than before.
4. Second coat on a sunny day. When it got sunny, I added more Flex Glue to the spot that was still leaking. The sun helped it dry. After that second coat, I haven’t had more leaks, and I consider the fix done.
I’m not going to promise any window is leak-free forever. This was a repeat leak in the same spot, the first coat cut it way down, and the second coat finished the job for me.
Bonus tip
I use a tire plug to unclog the used Flex Glue cap. I do the same thing for my caulking and silicone tubes.
A related leak, a different spot
This is not the same repair as my Promaster / Travato windshield leak. That one was the windshield. This one is the driver-side bed window.
What’s your go-to leak fix?
This post is based on a repair I actually did on my 2017 Travato. It’s not a professional RV inspection, and products can fail. Check your own seals, follow the product directions, and use your judgment.
