One Offs: mustaches and scuba mask seal

Turns out mustaches make it difficult to get a watertight seal with a scuba mask. I've been snorkeling and diving a bit lately and kept noticing water pooling in the lower half of my mask. Without any introspection I chalked it up to flaws in the mask until an older, mustachioed gentleman on my last dive boat asked me if I wanted some silicon gel to help the mask make a seal around my mustache. He had a little jar of it, kind of like the old Carmex compacts of yore, and with a light application in the furry upper-lip area I was able to maintain both my mustache (technically part of my total facial hair package, or, beard, more commonly) and my watertight scuba mask seal.
