Question: Do 2 coats of CP do anything more than 1 coat? I put 1 coat on and then put a 2nd on the butt section and began to wonder. Do I really need 2 coats?

In most cases, no. A wet first coat is generally enough to seal the thread. However, a 2nd isn't likely to harm anything. If I were putting a light colored thread over a very dark colored blank, I might go ahead and use 2. Although, you'd still be likely to lose a shade of color in that situation.

Hi Bruce,
Depends what thread your using. Stuff like madeira definitely needs more than one coat but most of the rodbuilding threads will get away with one. It's not going to hurt anything but you could do some testing on a scrap blank and see if there is any colour change with extra coats or any other issues with finish.

I'm just using the regular nylon Pac Bay brown thread.

Bruce,
Just so you understand. There is no build reason to put CP on anything.

The only reason that folks put CP on a piece of thread is to preserve the color. Other than that, there is no structural reason to put the CP on the thread.

If you use the regular Nylon Pac Bay brown thread, the finish applied directly to the thread darkens the thread and tends to make it a bit transparent.

I personally never put CP on any thread, unless there is a specific client request for the CP.

I much prefer to match the color of the blank with the thread in a finished state. So, I normally will pick a color that is a bit lighter than the blank. Then, when the finish is applied, the finish darkens a bit and tends to blend right into the blank.

If I want a color to stand out - I will use metallic, which also does not require any CP and the thread color will stay true with no CP applied to the thread.

I expect that you already know this information, but if not - I trust that it might help a bit.

Thanks, Roger. You won't believe it, but the reason I use CP is because it's easier to remove the thread and guide if I need to make a replacement. Is that a good reason? I replaced guides on a fiberglass rod for a buddy and it was so hard and painstaking to get the old finish off the rod I about blew a gasket.

Bruce, if you apply a little heat to the finish on the guide or wrap it will soften it and make it fairly easy to remove with a knife or blade.
