Finish for fretless acoustic bass fingerboard

[Peter Wilcox]

Followup on the fingerboard. 5 coats of alternating satin finish polyurethane (because that's what I had on the shelf) and sanding, then buffing with No.7 auto polishing compound gave a nice almost transparent finish. Time will tell regarding the durability. I've strung it with flatwound strings for the time being.

Thanks for all your help and suggestions.

Peter,
That looks great. I think most polyurethane takes about a month to fully harden up.
