Windshield Leak

[Morpheus122]

I've got an RV-6 - Slider with a water leak where the windshield meets the dash. You can feel a little air blowing through also.

What kind of sealant is used under the metal strip at the bottom of the windshield? Can I just run a bead of caulk at the joint?

The plans call for the windscreen to be attached to the fuselage with fiberglass, which also provides the seal. How is your windscreen attached to the fuselage?

There are several products that work in that application. Proseal and Lexel come to mind. Proseal is two parts, cures dark grey, and provides a very strong bond. Lexel is clear, one part, less expensive, and is more of a plexiglas safe caulk. You may be able to find it at a local home improvement store.

I'm sure there are other products out there.

Thanks for the quick answers. We have metal strips with grey sealant under them.

Do I need to caulk the seam or remove the metal fairin and reseal?

If you can simply unscrew the metal fairing, I would clear out the sealant that is there as best you can and re-seal with Proseal. No problem using Proseal on the plexi. I used it to seal my canopy here:



I might add that using Proseal as you see here protects the paint from erosion as well. The Proseal has been on this canopy for over 10 years.
