I am not positive, but from my reading, it is my understanding that I can grain fill with oil based grain filler and still be able to dye with alcohol based. Is that correct or am I misinterpreting things? If that is the case, would I be better to grain fill the ash and the end grain on everything and even though it doesn't really need it, grain fill the maple and let it take whatever it will hold, and then spray alcohol based dye? Like I said I have plenty of scrap to do my testing on and plan on doing plenty of testing, but would like to eliminate any ideas that would cause problems from the start.
