Post subject:  cleaning rosette/purfling prior to finishing

I seen to recall there was a discussion and maybe a tutorial by Hesh that outlined the cleaning of rosette rings when applying a colored or sunburst finish, but I am unable to locate it.
Hesh, can you or someone direct me to the discussion?
Thanks,
jack

I would imagine that there would be different methods depending on how you shoot the color. I shoot color onto bare wood a lot, especially with my sunbursts. I try to mask my purfs as best as I can to begin with, but some color always finds a way in somewhere. What I did was to take a 7/8" dowel, and make a cut in the end, which holds a razor blade tightly. I adjust the blade to the width of the purfling, with the side of the dowel againt the guitar side. I then carefully use the blade/dowel doomajigger to scrape the purfs.

For soundhole rosettes, I ground the end of an exacto blade so that the ground area sits flat when I hold it like a pencil. The ground area is slightly more narrow than the soundhole rosette, and I use that to scrape the color off....It is a real PITA. For the most part, I try to avoid spraying the dark part of the burst on the rosette.

I imagine, and someone will come along shortly that probably does this, it would be easier to shoot a base coat of clear, then tone with colored laquer. I believe the unwanted areas of color can be removed using a pencil eraser, or light scraping, followed by more clear coats.
