Epoxy Pore Fill question

When using epoxy (either silvertip or epoxy), I try to sand back the epoxy on the surface and only leave it in the pores. I'll start the process with sanding to 320g or so then using an air compressor to blow out the pores. The challenge that I run into is opening new pores in the process. I use a block of wood and long strokes in an attempt to avoid uneven sanding. Ultimately I'll get a good pore fill but I tend to apply several coats…

Are you having a hard time seeing when you have sanded just down to the wood ? If so, you might try a quick naphtha wipe. It should show off where the surface is still covered with epoxy. Due to the f…

Silvertip Epoxy on Stained Mahogoany Body & Neck

So, I've stained the body and neck and I'm in the process of applying several (3 or 4) coats of epoxy to them for pore filling. I watched Michaels video on the subject. My question is: When sanding the epoxy I beleive I should stay above the wood (stay in the epoxy) since it is stained, right??? When doing this same process on a body and neck that is not stained, I could sand back to the wood without consequence if I'm consistent…

Hi Gerry: Since you are starting over I would ask yourself if you really need to apply the stain to bare wood. It certainly can be done but more commonly the color is applied after the guitar is pore…
