TS720, I ordered a quart.

So did I. :-)

Is it possible to buy a pocket-size bottle with built-in brush, for
carrying in the vest?

What I do, is use a old, used up bottle of Loon Top Ride. This product
has small desiccant crystals, along with a Frog's Fanny/Cab-o-Sil type
product. I just recharge the bottle with TS720, and it's ready to go.
Pop the fly in the bottle and give it a good shake. The crystals work
the powder into the fly, and supposedly help dry the fly too. If you
don't want to buy a bottle of Top Ride, use a film canister. Scrounge up
some of those little desiccant packets you find while ripping open boxes
of kid's toys, or even in some food packaging. The desiccant is very
similar, if not the same as what's in Top Ride.

Does the fly have to be re-treated after catching a fish? If so, does
one have to carry the hydrophilic version as well, for drying flies?

Rinse as much fish slime off the fly as possible. I try and cast as much
water out of the fly as I can....and I might dry it off with my shirt.
At some point, the fish slime, water and Cab-O-Sil will combine into one
crusty mess. This is usually after several fish. If you're diligent to
rinse, dry, and treat, the fly will float about 10 times longer than
without treating.

Is it used the same way on nymphs?

I have not tried it on nymphs yet.
