So this is my first time using Transtint and decided that I'd try to do faux binding and a natural contour. I sealed the sides with several coats of shellac and then taped, but still got some bleed through on the contour. I've been sanding, filing, and sanding some more but it's still there. The faux binding itself came out nice, but the arm contour and the heel access contour have a little more bleed through. Should I just keep carefully sanding until I hopefully make it disappear?
