RE: [Paddlewise] wearing PFDs in hot weather

Silicone grease is available at all scuba stores. I use it for "moustache
wax" while scuba diving. Improves the seal. Do not use petroleum anything on
plastic or rubber! Be advised that not all silicone grease is food grade.

As for waterproofing binoculars, the problem is the vacuum created by the
change in temperatures. It might suck grease onto the lenses.

 Hi all!
A silicone based grease (eg. Dow Corning high vacuum grease) is perfect,
but may be tough to find. Try a bearing supply warehouse.  Petroleum jelly
or even generic automotive grease will also work, but even the "waterproof"
petroleum based greases will wash away after a few exposures so you will
have to re-apply occasionally. The silicone based greases are nearly inert,
and will last a long time. They're excellent for lubricating pump seals and
O rings too, and are suitable for drinking water filtration applications.
Hope this helps.
ByeBye! S.
