KLF 30 black satin finish, is it vinyl or painted veneer? in General Klipsch Info Posted January 29, 2020 1 minute ago, Maximus89 said: Nice job! Those black KLF-20s pop! Makes me want to get started on mine! I still just can't decide if i want to veneer them Walnut though. Thanks they turn out nice. If the veneer is solid, strip the paint and use Watco Danish Oil "Dark Walnut" or "Black Walnut". Finish it off with 3 coats of Behlen Satin Lacquer.
