Happy Weekend Y'all!  Gotta question:


I am thinking about putting a curly maple or curly koa binding on my next Indian Rosewood guitar.  I have noticed that Z-poxy tends to bring out the red resin in the rosewood.  It has never been a problem in the past because I have been using ivoroid bindings, and it is no problem to clean.  If I use wood bindings, though, I would expect to see some staining from the rosewood leaching resin via the Z-poxy.  I was wondering what some of you guys do to combat this, or does the wood binding scrape clean as easily as the ivoroid?

Oh, I guess I should add that I am not worried about the color of the Z-Poxy itself, just the resin from the rosewood bleeding over....I see where that missing edit button y'all keep talking about could come in handy!

Just finished a guitar with EIR, curly maple bindings, and used Z-poxy.  Didn't see bleeding, the Z-poxy did change the tone of the maple slightly.  Take a look:

Nice!  That's kind of what I am looking for.  Did you cut the first coat of poxy with any alcohol?  What I have been doing is cutting the first coat to get a good partial fill, then cutting the last coat less.  I think it is the opposite of what a lot of people here do, but it seems to work better for me as far as getting a good fill.  I'm getting quite a bit of bleeding onto the ivoroid though.  The alcohol in the first coat may be why I get the bleeding of the rosewood.  It's not an issue with the ivoroid, because it's easy to clean off, but I was concerned about any issues with wood bindings.  I also noticed that I get more disoloration if I move the poxy around too much.

Well - first, don't count me as an expert.  This was my second build, first time using Z-poxy (or epoxy at all).


First coats were not diluted, scraped them with an old plastic card (ID or ATM or something).  Wiped on the diluted coat last, roughly 50/50.


For what it's worth, this is what I had halfway through the process -

Thanks Todd!  Yeah, happy accident for me then, putting those together.  Was pretty pleased with the result.  - Bill

As Todd said, Zpoxy is thin as is no need to do a wipe coat to start.

Many of us sand back to wood after the fill has cured leaving the zpoxy only in the pores. Then we cut the Zpoxy either 50/50 with alcohol or 60 alcohol/40 Zpoxy as I do just to wet the wood but without leaving a noticeable film thickness. This is only to pop the color.

I have had some oily woods that did want to transfer color during the squeegee-on process of the Zpoxy. I seal the top and light colored bindings and purfling with shellac using a fine artist brush on the purfings prior to pore filling to avoid color transfer issues, but only when the back and side wood is a bleeder. The problem is not the Zpoxy it is the colored oils of the wood.

Well, maybe the next guitar...I suggested it to the customer as a no extra cost option and he wants to stick with traditional ivoroid.  Oh well, maybe I'll just build another one for myself.  I need an updated demo anyway.
