Pictures of the instruments I mentioned in a post on rec.woodworking.

The picture named "N7_4_Coats_of_KTM9_01.JPG" shows what the body of an
acoustic guitar looked like after the application of 4 coats of KTM-9 using
a 1-inch foam brush. I gave it a total of 8 coats before level-sanding and
polishing the body. I wiped down the body with Isopropyl alcohol between
coats to assist with the burning in of each coat to the previous one.
