canopy sealants

[scottmillhouse]

My 9A slider has been flying for over 6 years and I made no attempt to seal anything on the canopy since I was told they all leak, just use a cover. Coming back from Petit Jean I got stuck in the plane on the ground during a shower with water entering the side skirts and a steady flow from the rear skirt. I'd like to seam seal from the outside with a clear sealant. Existing threads appear to be focused for bonding or during construction. Silicon appears to attack plexiglass. Is clear acrylic tube window calk like from Home Depot safe? Ideas?

I used Sashco Lexel Elastomeric Synthetic Rubber Caulk to seal between the canopy and skins. I tested it first on a scrap and had no problems. It was mentioned on a thread on VAF.



I bought it on Amazon.

Thanks for the response......I'll give that a try. It sounds more suited than what I was considering.

Plain old Proseal worked great for me, I just masked everything off with electrical tape and applied it with a syringe and smoothed with a gloved finger. Left it overnight, peeled the tape and touched up anything I didn't like. Preparation must be key, it was way easier than I thought. About 30 min to put down the tape and another 3o mixing and spreading proseal. #1 rule: if proseal gets on a glove, get a new glove.


This is the only pic I could find of the finished edge (may have to zoom in), it's on the canopy and windscreen about 3/32 wide.

Lexel is clear and plexiglass friendly. Available at big box stores.

I used 3M 5200 with great results and its paintable.
