First time poster, amateur finisher. I have a kit guitar I'm working on; the body is basswood with a flame maple top. I'm planning on doing a dye job for the maple, and a natural finish for the rest. Since its maple + basswood, I'm led to understand it probably won't need grain-filler. I'd like to confirm this from you pros on the forum. I've had good previous experience applying tung oil finishes to homemade cigar box guitar necks. Will the dyed top take a TO finish well? Does the undyed body need any prep work before the tung oil, besides the obvious sanding? (Sanding sealer sounds like a bad idea for this particular job...) Any info would be greatly appreciated.
