If you are happy with whatever you want to use then i am happy. i was simply trying to help out with someones question and i have a fair amount of experience with the whole varnish-fly rod thing. I have listened to the whole resin/hardness/flexibility/UV resistance thing for a couple of decades and as you will note from a reread of my first post I did NOT say that ext would not work but that int was faster and easier to use, i liked the *generally* harder finish and it would yield an acceptable result.
Geez.....
