Updated Epoxy Pore Filling Demo - Video

Got a new way of doing something? Or maybe an old method that needs some clarification.

A new video I shot to demo using epoxy resin filling a mahogany baritone ukulele. Some might find it useful.

Thanks Allen, Questions:

1) which epoxy resin are you using? West Systems or Boatcote?
2) after the initial epoxy sessions do you do any sanding back?

I switched to BoatCoat several years ago and would never go back to WEST Systems.

For the first application I use their TPRDA thinning additive that really allows the resin to penetrate into the timber and get to the bottom of the pores. As I'm always building more than one instrument at a time, I will apply epoxy to one a little heavy, then go onto another instrument. Come back to the first and that resin will have sucked into the timber. I apply some more and work it into the timber and clean it up as in this video.

I sand back with P220 between reapplications. In my environment I can sometimes get a coat on in the morning and another in the late afternoon. But more often than not its just better to plan on overnight cure. If cooler than 20C you would want 24 hours.

It sands very well. Not gummy and no amines to worry about causing adhesion problems with your finish.
