Sun Gloves
Gnu Bee,
I wear a fingerless sun glove, it would help protect your index finger but mainly it protects both hands from the suns harmful rays.
The one I use has a thin leather palm, helps when getting a grip on both the rod and on a fish.
The Fly Fishing Shop has one something like mine and it extends the length of the index and middle finger of each hand to protect you from lines.
Personally, I would get these and if you need more protection then use the tape menthod to finish off protecting the finger.
Protecting your skin from the sun is really important and you don't have to use line damaging sun screen lotions on your hands.
