So after about three evenings of pumice pore filling, I finally got to the point where I thought I was ready to start padding on the shellac.
I spirited off the entire guitar with straight alcohol to (hopefully) clear all the pumice.
There were a few areas where some darker spots remained, which I took to be places where some shellac had started to build up.
I went ahead and did a first bodying session, and now those dark spots are there under the first layer of shellac.
Has anyone had experience with this?
Will they likely be removed or become less noticeable during subsequent body sessions and leveling?
Or do I need to deal with them somehow... I guess my only option would be to remove the first shellac layers (with alcohol?) and then continue on with the alcohol to scrub away those dark spots?
I realize pictures would be helpful, so I'll try to get some tonight.
Mostly just curious if this has happened to others during french polishing.
