About This Item

Gap-filling epoxies for permanent bonds. Our high-strength 2-part adhesives are activated when their resin and hardener components are mixed in equal parts.

Each 4-ounce set has two 2-ounce bottles, ready for mixing.

Fast-setting mixture has 5-minute working time. Full bond strength in one hour.

Slow-setting mixture allows 20 minute working time. Full bond strength in 8 hours, for a rigid waterproof joint.

Slow-setting black mixture is great for inlaying ebony fingerboards. 20 minute working time. Wait 3 days before sanding.

Note: With all epoxies, the slower the setting time, the stronger the bond.

Use adequate ventilation and avoid skin and eye contact.

Keep out of the reach of children.

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.

Does not cure hard

(Customer's Reviews)

I've bought two batches of the slow setting clear epoxy over the last few years. The first batch I used for inlays and it worked well. I then tried it to glue in carbon fiber rods in a neck. It stays soft and flexible no matter how long it is allowed to cure. I thought I might have a bad batch so I bought more on my next order. Same problem. I carefully measure out equal amounts using a digital postage scale in grams and mix it thoroughly. I'm very disappointed in the quality. Stew Mac should stop selling this stuff.


Clear Epoxy

(Customer's Reviews)

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.
