This is supposedly a "blow torch burnt" finish on an ASH body. I have a basic idea of how to achieve the "burnt" part....my question is this... Would you "burn" the body, and then still do grain filling, since it is ash? Or, would you grain fill first, and then do the "burn"? I would like to attempt this with a swamp ash body. Stain before, or after the grain fill? THANKS for any advice!
