Anybody knows a top notch tech that'd be able to apply epoxy to a fretless the Jaco style?
I don't know that it takes tons of skill to do it - from what I heard, Jaco did it himself. True or not I don't know.
Wow, what a beautiful work! But 10 months wait is brutal.
If you do it yourself, try System Three epoxy.:AOK
the guy at HG Thor Guitar Lab does good work from what i can see on his website.
he levels the board, applies the finish and then levels that and buffs it to a high gloss. probably not a diy job if you want the same kind of results he gets.
This is an easier process than doing a fret job IMHO. I did this to a Foundation S Peavey Bass just for kicks. I did not use Epoxy, I used Polyester resin, go down to any boat shop, I think I got a Gallon for $10 or $15 and the MEKP was like $6 or $8. You want buy the clear refined Polyester. You will also need to buy micro balloons, these are very small spheres of fiber glass that make sanding polyester possible, other wise it would be way to hard. USE DISPOSABLE EVERYTHING CUPS, BRUSHES, STIRRING UTENSILES, EVERYTHING. NEVER ATTEMPT TO REUSE RESIN, CUPS, STIRIRS, or BRUSHES. POT LIFE IS PROBABLY ABOUT 30 MIN ONCE MEKP IS ADDED.
pull the frets
Radius block the fingerboard till ultra smooth and even.
tape off the fingerboard and the neck, tape anything you do not want the resin to get on. Butcher paper everything else.
Get a Dixie cup and fill it about ½ way with resin and put as many drops of MEKP as the can tells you. Resin for this job goes a very very long way.
Mix carefully but well, you do not want air bubbles.
liberally paint the resin onto the board.
Let kick for about 45 min to an hour.
With a NEW dixe cup do steps 4 and 5 again and add the micro ballons to make the resin just a little on the thick side but is still smooth and flows and paint on as before. This is called hot coating.
The more care you take now the less sanding you will have to do later.
Wait 24 hours and sand. Should look like glass sitting on your fingerboard.
Hope this helps.
Polyester resin? Yikes, have you had any problems with it chipping? It can be brittle when cured so it's not typically used as a top coat. Usually it's used in conjunction with woven or matted glass fiber. If it works for you, cool, but I'd personally go with a UV stabilized epoxy.
There's another product that I've been using lately. I can't remember the name off hand but it's a clear epoxy sealer that has a water like consistency so it soaks into the wood. It doesn't build up like epoxy but if you want a durable finish with a more organic feeling fretboard, it might be the ticket.
No probs with chipping, 2 coats, even with the micros in the second coat are holding great...tough stuff.
I believe Pedulla Basses uses Polyester.
Read the bottom specs for the MVP.
Pedulla was the only reason I decided to try the Poly.
I played one at Guitar Centers and LOVED it!
Still... if anybody knows a luthier that can do it, please share the name.
