This episode of DIY's Handmade Music brings to a conclusion the four-episode guitar-building series. Featured in this episode is the precise application of a sophisticated wood finish to the instrument. It's an alchemy of applied elements, but luthier Lynn Dudenbostel shares a secret. A good finish is the result of what he removes not what he applies. As he says, it's not how much varnish you put on a guitar, it's how much varnish you leave on a guitar. 
The show then goes back to the Nashville recording studio where Cody Kilby, guitarist for bluegrass band Kentucky Thunder, gets to take the newly completed Dudenbostel guitar for a trial run. And just to insure a passing grade, host Jeff Wilson asks the expert on vintage guitars, George Gruhn, to evaluate the finished product. 
In this segment, Lynn Dudenbostel reveals the various techniques he employs to finish this guitar, following in the traditions of master guitar builders.
