I put a braided loop on fly line same as I always have except I used ZAP a Gap instead of Superglue for security. Fly line at connection  turned into a C shape. Great for a strike indicator but tough for casting. Any one else have this issue? Zap a Gap (ZAP) was not spray on, it is the brush on product. I started to experiment with adding a little ZAP  on fly line above leader to see if I could make a nice little bend for an indicator. I think I might hit a sweet spot but it seems like a shot in the dark right now. Fishing small nymphs for steelhead. Seems like a good idea right now.

I will do 2 nail knots and then just a very small amount of super glue or UV cure on the knot
 
I have coated the entire braided loop material with aqua seal and had it dry like you said... the issue being fly line is much more supple that dried glues
 

It made a nice strike indicator. I have been experimenting with gluing fly line with ZAP  in areas to see if I can make something useful without killing the cast ability.
