Bill, I like the info you gave, but it made me wonder, on fret work why not dip the piece in shellac, as opposed to spraying? Don't you have the same problem with getting coverage in the frets, spraying shellac? Could you dip in shellac, blow out the excess from the frets and wipe it off the face of the project? I have not done this, just wondering. There would not be nearly as long a wait time for it to dry and then spray on the whatever.
Also mixing the BLO 50/50 with Mineral Spirits works good and cuts down some on the cure time.
I also never read of anyone using Deft Clear Wood Finish as a top coat. I know it is not available in some places anymore, but it is what I use most for a top coat. Does a great job, dries quickly.
I love this place. I almost didn't read this thread, because this topic has been discussed many times, but, I did read most of it and yep, I learned some things again.
