I carry it but don't use it much. I use a smear of it on the tippet or
leader knots to help locate a small dry under harsh lighting or when I'm
drifting an emerger or soft hackle just under the surface. I serves as a
visual indicator but isn't a bobber like other indicators.

Same here. Seems to depend on temperature. The putty-type indicators work
better in warm weather than in cold. In really cold weather you damned near
need a coal chisel to get the putty out of the container. Also, as has been
pointed out elsewhere, it can leave a sticky residue on the line. It can be
useful when you need to make a point on the line a little more visible, but
I like yarn. Make a loop in the line, insert a little piece of colored yarn,
and you have a very good indicator.
