I mentioned in another thread that Jake will be performing at a venue close to my home in October. I am thinking about asking him to autograph my Lanikai LU-21T which has a satin finish. I have read some other threads on the topic that discussed the fact that sharpies can run and/or fade. I am looking for additional thoughts on what type of pen I should have him use and what type of spray-on lacquer I should use to help protect the autograph. Thank you in advance for any thought and tips.
