Here's a question from the Volume 4 - Issue #6 issue of RodMaker magazine:
"I'm an amateur rod builder, and I started off using Flex Coat
Rod Builder's Epoxy to attach grips, reel seats, etc. I have just
gotten to the point that I feel proficient at using this relatively
quick-set epoxy. I now feel fairly comfortable with it.
However, I've been hearing great things about U-40's Rod Bond, and
was thinking of trying it. But, it's a paste and I know nothing
about using pastes. Here's my question: How far superior is
Rod Bond to Flex Coat? Is there a difference in strength and
longevity? If so, is it such that it makes any "practical"
If Rod Bond really makes that big a difference, I'll switch and
just learn how to use it. If the difference is minimal, I'll
probably just stick with what I know.
Thanks for your help. I'm sure there's a magazine article
where you compare the various grip epoxies, but it's not in
any of the magazines I have." Andrew . . .Siloam Springs, AR
Both epoxies are excellent for rod building tasks and both are more
than strong enough, and durable enough, that they are interchangeable
for most assemblies. But there is also much to be said for having the
right tool for the job.
I have been using the Flex Coat Rod Builder's Epoxy for many, many years.
I find it to be excellent for assembling grips, handles, butt caps, etc.,
etc. But there are times when I wish it wouldn't run or sag, which like
all liquid epoxies, it is prone to do. That's where U-40 Rod Bond comes
in. It was specially formulated for performing rod building related
assembly tasks. One of its major perks is that it stays where you put
it! Being roughly the consistency of a gel, like vaseline, you don't
have to worry about it running or leaking out of your joints or seeping
into your cork or grip materials. It can be used in nearly all rod
building related tasks with outstanding results. And why not - that's
what it was made for!
So is one better than the other? That depends upon what you want your
epoxy to do. Both are more than adequate in terms of strength and
longevity although they do possess slightly different properties. Thus,
it boils down to which you find more helpful in your rod building
Personally, I keep both on hand. I find myself using the Rod Builder's
Epoxy for adhering cork rings and installing almost any type of grip
to the blank. The U-40 Rod Bond is what I reach for when I need to
install a reel seat, uni-butt gimbal or butt cap. Either can be
substituted for the other and be expected to work fine on a fishing
rod. But I think you'll find that when it comes to any particular
application, you may find one is easier than the other to work
with. Epoxy doesn't "go bad." I'd keep some of both on
hand and use whatever is easier depending upon the task at hand.
