Best Oil Based Wood Grain Filler For Mahogany Guitar Project:

Why oil based? Water based fillers work extremely well and a whole easier to deal with. And the water based filler accepts staining a lot better too. The water based Timbermate stuff is really good.

I guess it just bugs me putting water on a wood surface that I'm going to seal.
 
Mohawk Grain Filler. I have it in both clear and medium walnut. Used the medium walnut for the T-Bird bass, to go with the antique cherry (wood, not color) stain. You can get it in many shades, or just get the clear and add stain to it.


This is what the walnut filler looks like under the cherry stain and clear lacquer. Don't have any photos of just the grain filler sanded out.

Robert, you're over thinking this. There is very little water getting mixed with the filler. Maybe a tablespoon of water per coat of filler. The water based filler dries very quickly, then it's sanded down even further. And especially with raw mahogany, and before grain filling, you need to apply a semi damped rag or towel and wipe down the mahogany body. When it dries, the surface should feel a little fuzzy because the partially attached broken fibers from previous sanding will now have swelled and have an erection. You will need to sand with the same or slightly finer grit to knock off the proud fibers. All this will help will with the final finishing.

Great information!!!

I plan on sanding much smoother than the 220# I see people recommending.

Wow!

Looks great!

So, filler, then oil based cherry stain? That's giving me ideas.

I'm wanting a dark brown grain filler, then probably a dark mahogany stain, followed by boiled linseed oil, topped with dewaxed amber shellac and topcoat with lacquer.
