Hobbyist needs a very hard finish for a fretless bass fingerboard

April 3, 2010

I am in the process of refinishing the fingerboard of a 1953 Kay C-1 upright bass. The wood is rosewood and has been sealed. Since the finish has to stand up to long-term contact with metal strings, I want to create a very hard, clear finish. A local luthier suggested I use polyester, preferably in a spray form and to apply several coats, sanding between applications. When all coats have been applied, sand with progressively finer grit and finish with rubbing compound. I have not been able to find a local supplier for clear polyester. Can you help?

All the best,

I would suggest using a polyurethane wood finish. It will be harder than polyester and easier to both obtain and apply. Any hardware store will carry water and solvent based polyurethanes. A solvent based product would likely be the most durable.
