Once the ports have been stuck on the nose more than a second or so they simply won't hold if reapplied (been there done that).
The adhesive just isn't very forgiving in that regard. I suppose if it were more forgiving then we would be bitching about it taking off 3 or 4 layers of skin when we removed them.
I am not giving up though. Still have some different things to try in my little bag of tricks when someone really wants to make it work.
I have strongly encouraged OP to reach out to Stuart for additional ideas beyond what I have thought of.
The facial hair thing does complicate things just a little bit but it isn't something that is impossible to solve. Stuart has a goatee himself so some first hand experience there. It can work.
He should get the P10 hose Friday to try to see how much it helps or not and will go from there.
When the Bleep sticks and it's properly connected....it simply doesn't leak. Adhesive failure can happen but for the most part it has been extremely rare for me. For me rain out has been the main culprit...water in the nose piece itself which is pretty much a guaranteed failure waiting to happen. I have to find a working compromise between room air temp, humidity level preference and hose air temp.
I am not crazy about warm air in the summer but sometimes just a 1 degree change makes a big difference.
Like I have always said...nothing is ever totally perfect and often it's a work in progress but the rewards are worth the extra work in my book.
I may have to RISE but I refuse to SHINE.
