When I shellaced a top the bloodwood around the Rosette bled into the Spruce.I`ve re-sanded and things look okay,but I`d like to get a coat of shellac on before the finish goes on.I`m gonna try that Emtech 6000.Do I dare risk it bleeding again or is ther another solution?

I would be very careful using CA around the soundboard. If you get it on the spruce top, you will have a yellow stain that you can't get off.

I don't have a solution, but every time that I hear that Bloodwood bleeds I think about the irony.

I went through this not too long ago and there's a lot of information in this thread:
http://www.luthiersforum.com/forum/viewtopic.php?f=10101&t=22956&st=0&sk=t&sd=a

I was trying to avoid spraying but it just turned out that the best solution was to spray several light coats of shellac.

Jose Oribe is a top classical builder. Years ago, when he was a one man shop, he wrote that his wife helped before he finished by using a small artist brush to paint all the purflings with a laquer that would prevent bleeding. So, test your wood species with a laquer and maybe you will want to do that.

If you don't want to get out the spaying equipment for such a small job, you can french polish successive thin dry coats of shellac. Use a small piece of rolled up t-shirt and keep a fresh surface. Let it dry between coats. Two or three are fine. I watched Kenny Hill's french polisher and he was done in a jiffy, moved right into the whole french polish job from there.
