I'm going to be doing my first finish soon. Flame Maple top on a White Walnut back. I am wanting to color only the top and apply a clear finish to the back. Is it simply a matter of taping the top or is there other prep work involved? What dyes are preferred? I've been looking at either MEK or Trans Tint dyes. Oh, and what is a good choice for grain filler? Any advice, suggestions, pics are appreciated! Thanks!
