Does glue/head cement affect action of a fly?

[downriver79]

I've got some commercially tied Hoh-Bo speys that have no cement on the thread at the front. I got a fresh one snagged between some rocks the other day and must've compromised the whip finish and caused the thread to start unraveling. I was thinking of coating the rest with a thin layer of Loctite gel super glue as a preventative measure. Is there any reason, from a performance standpoint, not to do this? I'm assuming the manufacturer (Solitude) didn't apply any as a means to save $, but just wanted to check with those of you who actually know a thing or two about tying flies. Thanks in advance for any input!

As a big user of Hard as Nails and UV cures, I’d say no. Both certainly help flies withstand a beating.

I'd noticed Hard as Nails still has a scent a couple of days after tying, and figured: If I can smell it, I'm sure the fish can too.
I've stopped H as N using in favour of super glue (or UV coating , if I need a built-up head).

When I was using head cement, I used Hard as Nails. Nowadays I don't use any head cement because most of my still water patterns have a bead head and I double or triple whip finish to keep the thread in place. So far, the multiple whip finish technique works fine.

No doubt it has a smell, but I’ve caught hundreds of coho and searun cutts over the years on flies smothered with it. Maybe it is the head cement equivalent to WD-40.
