Lot's of books to choose from! I've listed some I found from Amazon
below. I want one that covers mixing finishes like wax topcoats on
Danish oil, or shellac as a top coat, etc. I also want a chart (that
I've seen somewhere but don't recall) that compares various finishes
in terms of durability, repairability, water resistence, shine, etc. I
don't care about spraying techniques, I'm only doing hand
finishing....

BTW, I'd welcome a recommendation from Jeff Jewitt, a sometimes
contributor to this group and the author of many of the books listed
below. Jeff, are you out there reading this?
