On my last few restrings I just used a plain old oil based non-tinted varnish & swabbed the holes(no more than 2 at a time)using the afore mentioned q-tips. Like you I pre-soaked the bushings in the PDF as well, more for color than any other reason. Mike -- It is the mark of an educated mind to be able to entertain a thought without accepting it.
