Coloring epoxy for guitar inlays

A little bit of glue hides imperfections... Dan Erlewine personalizes a fretboard with the customer's name in pearl: "Hoss." There are small gaps around the inlays, and dan shows how to make those gaps disappear. Dan also shows a neat magnet trick for cutting thin slices off the end of a fretboard.

Clear Epoxy

By Red Fox Guitars from Albert Lea, MN
(Customer's Reviews) Sunday, February 02, 2014

Wait up to 3 days before you start sanding or grinding away at it. I found out the hard way, then accidentally found a little "info box" in one of the previous catalogs saying to give it a few days to harden up. The bottle says 8 hours, so I gave it 24 and that wasn't enough. Somebody needs to get there directions straight, but the product works if you give it time and it really doesn't take much. I will buy more when my supply is gone.

Slow Setting Black Epoxy for inlay work

By Dan Selchow from Norman, OK. USA
(Customer's Reviews) Tuesday, October 15, 2013

I purchased the Slow Setting Back epoxy on the chance it would work against a light colored wood. I was inlaying some abalone into some yellow heart. I tested it first on a scrap of wood. I was very pleased with the results so I proceeded to use it to fill the voids once the abalone was glued in place. This product will black out the background when used where it is less then .050 thick. I would highly recommend this product for this use.

Use only for fill

By brhsr60 from florida

This glue is not a good choice for anything but using as fill. I have tried several times unsuccessfully to use it for other purposes, I.E. gluing wood joints, and it has failed miserably every time. I would recommend staying away from this product.

Works well, but the black part has turned into a paste, making it impossible to squeeze out. still mixes with clear part so I don't plan on purchasing more.

used with black or brown powder coloring, this fast setting epoxy makes a good filler for small areas as well as a strong adhesive for some situations Has a very long shelf life.

think again for slow-setting

By emily sablosky from san diego, CA
(Customer's Reviews) Wednesday, October 12, 2011

I've tried the slow setting epoxy a few times in both Southern California and New York (different climates!) and I can't seem to get this epoxy to hold a permanent and strong bond, regardless of it being right when it's opened or when the shelf life has dropped off a little. I've (carefully) tried changing the ratios slightly from exact 50/50 and mixing in various quantities and I just don't trust it.

Most things from StewMac really measure up but this one product doesn't. I would definitely recommend something else for jobs that call for this sort of adhesive.

Black Epoxy for Inlays

By Denton Specialties from Chappell Hill, TX
(Customer's Reviews) Friday, October 07, 2011

I routed out the cavities for the delicate inlays with a hand-held Dremel, and I must say it looked like rats had chewed out the wood! I used this epoxy to glue the inlays in and by the time I had sanded them level, and sprayed on the clear-coat, I literally could not see any ragged edges.

Great product.

It dries quickly, and it's very stout. It works really well for fixing stripped threads on softer guitars and repairing damages.
