Winter Build Off 2025 Tele

I'm thinking of using epoxy to grain fill on my current build, what's your method of applying it?
I use either a cheap brush or cloth wipe, and brush or wipe it on. Then I take an old credit card or other plastic card and scrape it smooth. That helps prevent drips and runs, keeps the coat thickness to a reasonable depth, and pushes the epoxy into the grain and/or divots.
 
The body was ever so slightly still tacky this morning, so I'll let that cure until tomorrow. It was chilly last night. I worked a little more on the headstock. I think I'll leave it at this point.

I use Wool Daubers:


I like them better than brushes or cloth. They soak in the epoxy, but not so much that it flows out everywhere. They will push the epoxy down into the grain, but only leave a thin coat on the surface. Not as much mess. I use them for applying epoxy on surfaces of laminations and for filling grain.

When filling grain, I don't usually squeegee off the excess on the surface. As the epoxy cures it will sink down a little deeper into the grain. If you squeegee it, it will usually end up sunken in the grain, and you'll have to do another coat. So, I use the dauber to leave a thin coat on the surface, and let it cure like that. It's a little more sanding, but I can usually completely fill the grain in one epoxy coat.

I tried using those wool daubers a couple of times. They didn't seem to work for me. I seem to remember the epoxy "bubbled up" for lack of a better description. And cured in its "bubbled up" form. I had to sand it off almost entirely. I tried it more than once. I'm not sure what I was doing wrong.

Hmm....You were probably squishing down too hard on the dauber. I use the daubers with a light touch, gently sliding them over the surface. I don't try to smash the epoxy down into the grain. Just brush the dauber over it and let the epoxy settle in. The dauber leaves a thin coating on the surface.

I did a bit more sanding and applied a final (hopefully) coat of epoxy. I'll need to stop by HD at some point to buy a couple of spray cans of the Varathane Poly. I'll put a few coats on the body and neck, and likely leave a satin finish.

You also could leave the epoxy as the final finish. Level sand it and scrub it as if it were poly, to whatever level of sheen you want. If you like the color and appearance, you don't really need to put poly over top of it.
 
Went to HD this morning and picked up a can of Varathane.

Sprayed a couple of coats on the neck this afternoon. I'll sand the body a little before I decide if it needs any poly.

I love these Varathane products. Easy to work with, time proven, tough and remains shiny after many years.

Did I mention they are very wear resistant ?

It's amazing how well I can see all the imperfections in my finish...

only when I get to this point in the process. I'm even seeing some deep scratches in the wood, from when I was initially leveling it. So, do I sand it smooth now, and refinish, or just do the best with what I have, assemble it and play it by this weekend? Stay tuned for the stunning conclusion of this episode of mapleglo's 2025 build-off tele build...
 
It depends on the results you're after, I guess. If you can't see the imperfections from a distance and they don't really bother you, just leave it.

Me being somewhat OCD with finishes, I'd sand it down and put a lot more finish on, sanding between each coat.
