I just bought a fretless MIM Fender Jazz and am intending to coat the fretboard to give it a more Jaco/Buzz Bass tone. But I need some help from those who have done this. 1. In the recent BASS PLAYER article on do-it-yourself fretless, they recommend using a polyesther surfacing agent. Does anyone who has done this have a product name recommendation? 2. In previous threads on this subject, folks have talked about sanding this to a high sheen. Before I ruin my bass, I'd like to have a bit more specifics on the sanding. Did you wet sand or dry sand? What paper did you start with and what did you finish it with? 3. If there is any sage words of advice you can provide based upon your success or failure, please let me know. Thanks for your help!
