Just wondering if anyone else has encountered this. I am fairly new to
french polishing but I think I've gotten the hang of it by now.

I am sure that most of you know that LMI's white instrument glue is
soluble in denatured alcohol. And DA is the biggest component of a
shellac solution.

Well, I have noticed that when in direct lighting, you can see faint lines on
some of the glue lines. Primarily on the front of the guitar (Rosette
especially) where I didn't use epoxy as a pore filler. And of course, I have
used LMI's glue - I'm wondering if anyone has had this happen before.

Is this another situation like Titebond and KTM-9...the finish will
evidently "sink" around any glue joints if you use that combination.

I am not too worried about it as the lines can only be seen in direct
lighting and this particular guitar is being built for a friend at cost.
However, I wouldn't want this to happen to a guitar for a paying
customer.

Any insights?
