New to the forum and my first post, so go easy on me if I ask questions that have been answered before. Just recently ordered my first full Warmoth build. It's a swamp ash WGD with bookmatched swamp ash top, flame maple w/rosewood neck. I am planning to use clear grain filler and hand rub a tung oil finish. Does using grain filler affect the look of the grain in any way ? I guess what I mean is , does it dull or alter the look of the grain ? Still got three or four weeks to wait but I thought I'd ask before it arrives.
