I don't make that many rods but when I do I like it to be a well designed and a well executed creation.
What are the advantages and disadvantages of thread cover with either epoxy or Permagloss?
Is one better than the other - why?
If one is better why do we do both - there must be something in each process?
I am soon to be making a rod for myself and it wil be an expensive task and I am considering Permaglossing the threads
Help me out here?

Permagloss is like water, super thin, no-mixing, cures very fast and stinks to high heaven. It leaves a very thin coat on the wraps and gives that "old school" look where you can still feel the wraps (unless you use numerous, numerous coats). Epoxy is thicker, requires careful 50/50 mixing, takes much longer to cure and covers thicker with less coats giving more of a glass look. I don't know if one is better than the other, they each have their own unique uses. Permagloss is usually easier to use for coloring blanks while epoxy works better for marbeling. Randy.

Robert,
I am not an expert by any means. And there are others here that can give you a more complete answer but I will share my feelings.
I have used both. My wraps finished with one coat of epoxy look better - smoother, more even finish, cannot see or feel threads.
My wraps finished with 2-3 coats of PG are not as attractive - see & feel threads. If I use more coats I can't seem to get as even a finish as the epoxy because it dries so fast it does not flow.
But, and it is a big BUT - I am concerned with weight and how it affects the action of the fly rod. I also wish to use ceramic guides. So just to keep the weight as low as possible I am happy using 2-3 coats of PG .
Also, studies have been made - and you can find them on this site - that shows PG to have much greater adhesion properties.
Bottom line - I use PG for my personal rods for performance.

I am fairly new to this craft too. I have been using Guidebrod 1 part rod finish on my thread wraps. It is thin and requires several coats but it does not give off fumes and dries fairly quickly. After 3 or 4 coats the finish looks smooth and has a nice shine to it. The lack of fumes is what I like best about this product. The rods I have put together work well so far. Any long term issues with this product that I should be worried about??
Thanks
George

PG is stronger than thread epoxy in unifying the threads so they can achive a greater potential of their overall strength before the guide foot slips out due to stretching of the threads, adding epoxy increases the hold, more specifically lessens the stretch by a factor of 6, taking some 27-30# of pull (At a 30 degree angle) remove a guide, permagloss has an even higher rerturn. PG is air cured and saving it once air replaces the product in the bottle can be difficult, there are ways to combat this occurance, I've added BB to bring the fluid level up to full before, but also had several bottles once opened rock up solid,(even kept full) resulting in tossing them. PG is also a great finish restorer and uses the moisture in the air to cure.
