I flew the other night and felt cool air seeping in around my windshield. Seemed like it was coming in the top portion.
After landing I looked closely and it appears that there is some rubber (latex?) caulk around the windscreen. But it appears to be old and is fraying.
I'm thinking of cleaning the old caulk off as best I can and running a new bead of latex caulk around the windscreen. Comments for/against this?
I see on other posts that silicone can advance corrosion. And that there is no felt seal on the top of the windshield. If that's the case, what seal is used there? (Sorry, I don't have my parts book at home to see what type of liner or retainer is used for the windshield....)
What have other's done to try to minimize windshield leakage?
I have done the duct tape routine under the inspection covers at the wing roots. And I've got foam inserted into my air vents. Any other tricks to stop windshield leakage?

Kyle, the upper windshield does have a seal. The Cessna seal is felt, but you could also use a foam seal as used on Pipers. Good source of info and products at: http://www.lpaero.com/accessories.html
They also have recommended sealants.

make sure the center post in your windshield is not cracked or broken. mine broke and the windshields moved around pretty good especially on starts, no sealer would hold up to it.
same problem if you've gone to a one-piece, they tend to move around at the top

The windshield should "move". It's a floating windshield, and if it were rigidly sealed to the airframe would crack and split.HA wrote:make sure the center post in your windshield is not cracked or broken. mine broke and the windshields moved around pretty good especially on starts, no sealer would hold up to it.

Sealant has the unfortunate ability to contribute to cracking due to this. Felt is the original and the best stuff, as it also will dry out and "wick" moisture out of the joints and be less likely to cause corrosion.
