Craig has asked for an update about the finishing process so I thought I would post a few progressive photos. I am starting to get the hang on brushing on the KTM-9. I am confident that the thinking of less is best is the way to go. I was trying to get thick and well covering layers of lacquer on each time but I have found that the bubbles or drips that go along with the thicker coats are harder to deal with once they have dried.
I also found that the KTM tacks off rather quickly and touching the area again can result in disaster. The latest coats have been thin, light and imperfect but I no longer have drips or air bubbles.
I have now applied about ten or twelve coats now and rubbed back the higher points with 340 paper about every 3 or 4 coats. I’ve also noted that the sand paper doesn’t seem to last very long – which was surprising. I am most likely using the wrong type of paper.
The photos below I took today and I am thinking that tonight, I will sand the surfaces back until there is no shine left of the surface. Please keep in mind that with these photos I have tried to take images which show the flaws in the finish. I have turned the piece so that all the brush marks and thin parts are visible.
In general I am happy with my first effort at finishing. Those that have seen the guitar have all commented on how good the product looks. Maybe next time (planning is underway) I will spray but I think that brushing KTM-9 is suitable for the home builder to brush on.
