    When I wash my plane and windshield I put a strip of 2" blue masking tape across the bottom of the windshield. I didn't think about putting a channel on the inside, that's a good idea.

    I normally clean the bugs off the windshield with a spray bottle and microfiber cloth.

    Thank you John. I really enjoyed this part of the build. The baffles are done in white powder coating. The white makes it easy to see if anything is leaking or cracked.

    Just wondering out loud whether a "P" seal attached to the inner edge of the boot cowl that butts up against the windshield might work. You'd need to have a bit of pressure against the seal to compress it to form a water resistant seal. I haven't got to this point yet (couple of weeks off) so not too familiar with the geometry but would it be possible to put screws through the boot cowl and windshield into anchor nuts bonded to the inside surface of the windshield ?.

    Does velcro make a waterproof seam? Has anyone tried it? Just thinking out loud.

    Velcro is not water proof. It will resist flow through it temporarily. In my experience, water weakens the bond between the two surfaces. I have lost stuff while SCUBA diving this way.

    This question resulted in me removing the cowl and evaluating what behind the panel is vulnerable to possible water drips. The only thing that extended forward of the windshield was the altitude encoder and only about 3/4" of one corner. This was evaluated only considering the exact area below the lip of the windshield. I had also recently washed the airplane to prepare it for our local hot rod and airplane show here. I carefully inspected anything in harms way for any evidence of water - lots of dust under there and found nothing. Because of many vulnerable areas wing roots, turtle deck, horizontal stabilizer root fairings, etc. I try to be prudent with the hose.

    You are right Lowell, the water dripping problem depends a lot on your layout of the electronics bay. I was thinking mostly about my layout that has two shelves that extend under the drip line with things like xponder, engine instrument module, etc. mounted on them. If a person were planning to leave that area unsealed you could deliberately mount vulnerable items out of harms way.
