    They didn't have System 3 epoxy at the store I was at, so I asked for a substitute and they gave me "Shellac Traditional Finish and Sealer".



    Thanks in advance.
  2. I have absolutely no idea, however, shellac is a very very different substance than epoxy.

    An educated guess would say that shellac would be the equivalent to the finish on the back of your neck rather than an epoxy.

    Would that be a bad thing? Should I find a harder substance?

    I would not shellac a fretless fingerboard.
  5. It isn't so much the hardness of the material, it's more about durability.

    The epoxy is kind of like a hard rubber type of material.
    Just like the tires on your car, it isn't very hard, but it is very durable. As the strings grind into it, it can sort of spring back after a while.

    Okay thanks for the help, I think I'm going to have to go back and get something else.
  7. Shellac is very easy to use and gives a great finish but if you're looking for durability because you want to use roundwounds on a fretless fingerboard, then epoxy is your best bet. I've gotten great results using Envirotex Lite.

    Shellac is not hard enough or durable enough for this application.
    Epoxy has two parts... hardener and resin. I have not heard of three part epoxy. Readily available. You can order it on the web. Nasty stuff. Do some reading before you try this.
  9. System Three is the name of the company.
  10. This is the epoxy we use at work for gluing medical device parts together - Loctite 0151 2-part epoxy. Has a long fixture time, almost an hour, and full cure is generally achieved in 24 hours. We cure our parts in a large walk-in oven at 135 degrees F to speed things up and it usually takes about an hour for full cure. It mixes to a cream color and is extremely hard at full cure. I plan on using this stuff when the time come for me to do my own fretless.

    I would buy some fiberglass resin and use that. I have done a few fretless necks with good results. You will have to tape the sides and end of the neck to hold the resin in untill it cures because it will flow level on the fretboard. When cured remove tape and use files to shape the radius. Use a long carpenters level with fine sandpaper glued to it to level the fretboard when done.
