Always kind of amazed that you guys have enough confidence in your process that you do not seal the inside, Totally sealing it is difficult of course, but bare wood, especially plywood’s endgrain, is a sponge.
For the vents I use the R62-5088 and the R625150 thumbscrew.

No experience with goretex vents
I also made a rear brass vent for cross ventialtion for when it inevitably gets water inside, but I also have removed it somewhat regularly and rig up a computer fan to suck dry desert santa ana air through it… Condensation can form inside even if the skin is never punctured.

I/ve never tried installing a vent afterwards, always before the deck panel gets attached.
I modified the brass insert(1/4-20 internal threads) and made my own stainless ‘grub’ screw. I meant to order a brass grub screw. I use Vibra-tite v3 thread locker to seal it, with a smidge of Amazing goop over both for extra insurance. The amazing goop can peel off if one gets a sharp chisel shaped tweezer under it. The vibratite never fully dries, kind of like feathering disk adhesive used on sandpaper and powerpads.
I modified the thumbscrew vent receptacle so it would appear smaller. The nose vent is pushed as far forwards as i can get them for maximum drainage, as I consider water getting inside an inevitable. The only HWS That is no longer, is because I used Balsa inside of it and did not seal it adequately. The balsa turned to heavy mush.
