Posted this in the wrong forum and I apologize if this has been posted to death, but this newbie guitar finisher could use some guidance. I recently purchased an unfinished swamp ash tele body, and in my haste I neglected to use any grain filler or sealer and sprayed a few coats of the Stewmac Colortone nitro lacquer onto it. The more I'm reading on the subject, the more this is seeming to be a mistake. I still have not done any coats of gloss or anything. I am wondering if the body can be grain filled after lacquer has been applied? Or have I gone too far already? I'm not really requiring the body to be bowling-lane smooth, but I just want a nice finish. What would the drawbacks to a non-grain filled guitar be? Just non-smooth finish? Any advice you seasoned finish experts could provide would be of great value.
