Just got me some Timbermate grain filler for an ash body. I have thinned some out and spread it on a sample piece, and it worked and looks great. But I later intend on adding a dye or stain to the wood. Any tips? They claim it takes stain, does that mean it will take the color just as a similarly colored wood would? Does it take dye similarly? Any suggestions or warnings from those who've used it before would be appreciated. Thanks!
