I would like to refininsh my heresys but I'm hearing all this stuff about sanding throught the veneer and I'm kind of changing my mind about doing it. I have birch heresys that were finished by the 1st owner. I thought that with the birch heresys there was no veneer and that it was solid wood, not plywood. I am right or is there a veneer on them? In case this makes a difference they were made in 1979, I think.
