Hi all-
I am working on builds #6 and #7 and this is the first time I have tried the "dark dye, sand it back, light dye" technique. I am working on two guitars, both with figured maple caps. One was dyed black, sanded back and then dyed blue. The other was dyed reddish brown, sanded back and then dyed amber. My method was:
Sand the body to 320
wet it and let it dry to raise the grain
knock down the grain with 320
wet the body
apply the dark stain to the whole body until the color is pretty dense, let it dry
sand back the dark color
wet the body and apply lighter dye
work with both colors until it looks right.
Dye is transtint in water. 25 - 40 drops of dye per 25 ml of water.
I tried everything first on scrap pieces and it worked fine with both colors. The blue and black body came out great.
However, on the reddish brown / amber one I am getting tiny 'dots' of color that appear about 5 minutes after I am done. It seems like there are still tiny reservoirs of the darker dye left in pores and the light dye is bringing it out, but I didn't have this problem on the test pieces or the other body. I have sanded back and re-applied the amber 3 times and I keep getting the same result each time with the same intensity. Does anyone have any suggestions on what to do from here?
Here is a photo of the body:
and a closeup of the dots:
Any suggestions would be appreciated!
