I'm starting a project to build my own solid body guitar.
I received the body and its made from ash. It needs to be filled (the grain is very porous).
I hear that I need wood filler for this.
The plan is to stain the guitar with a walnut stain and then finish with an oil finish (no lacquering and I want the grain to show through).
So my questions are, does it matter what wood filler I get? and all wood filler can be stained, right?
I've heard that a darker wood filler will accentuate the grain and give a greater contrast between the areas of the grain. However, I also had some advice that I should fill the wood in a similar colour and stain over the top.
I'm quite confused and don't want to get it wrong. I would like the grain to show up as much as possible, but don't want to ruin the staining by putting the wrong filler on it.
