Hello all, I am new here and after reading these and other guitar finishing forums I have a question. I just ordered my first body from Warmoth. A thinline f hole tele, rear routed with standard thinline controls. Black Korina back and top. It will be finished natural with tung oil. Here,s my question, Before I put on stew mac black water based grain filler, do I put the 50/50 mixture of tung oil and mineral spirits. Some of the stuff I read says to put it on first, lightly sand and then grain filler. But then I read grain filler first (3 or so coats) then 50/50 mix. I have also read 50/50 mix of tung and varnish. I have never used grain filler before and wanted to know what has worked best for you guys that have used it. I was told 4 weeks out for the delivery of the body so I will have time to experiment on some test peices but no Korina so I can't be for sure.
Thanks
