Assuming that light reflections from a shiny rod surface or from the finish on the windings can spook fish, I conclude that matte finish is the best way to play it since fly fishing involves more close quarter fishing. You may never need it; but if you need it, you have it.

But not all blanks are matte finished. Is there a safe way to dull the finish on a shiny blank?

And, of course, what is a good product to use to put a matte finish on the rod windings?
