I’m working on the StewMac guitar build. I got some black grain filler from StewMac because I wanted it to get down into the wood so that when I sanded it off, it’d show the grain more when I apply red stain.
It worked, but… the grain filler got down into the pickup cavities, and it’s turning out to be crazy difficult to remove it. I should have masked them off. Live and learn. The grain filler that I can’t remove will now be there forever. I mean, it IS a $200 kit after all. I’m not experimenting on a Core model PRS.
A couple of other things about the StewMac grain filler – it’s very difficult to mix with water, it smells kinda bad, and the directions to take it off with 320 grit sandpaper are laughable. You need 220 and a sander. All of this will be in an upcoming video.
Now I understand why Sully of Sully Guitars said “Grain Fillers SUCK.” Yes, I agree. They do suck.
