What kind of super glue is best. Now I'm a little confused here.
CA Is the Same as super Glue, which is the same as the stuff that comes in tiny bottles that require refrigeration correct?
The thing is, it started marking even a week after i applied the polly. Maybe i didn't let it dry long enough. Anyway i'm done with poly.
Any advice about sanding the current surface and applying the CA after?
I don't know about refrigeration, but yes. Krazy glue, super glue are just two different names for cyanoacrylate (CA) glue. As far as what kind is best, I don't think it much matters. I just used plain ordinary loc tite brand, but it shouldn't make much difference.
It does harden crystal clear, and polishes to a nice shine. (Like in the two photos I posted above).
Polyurethane should be pretty tough too, but depending on variety it may need more time to cure. Also, if you put on the additional coats too soon you can run into problems. It doesn't melt together like laquer. If you recoat it too soon the bottom layers won't harden, since the solvent gets trapped in.
I coated the body of my bass with minwax wipe-on poly, and it felt slightly weird (not quite tacky, but almost) and had a bit of odor for about a week. If that was on a fingerboard, it probably would have worn off in that time before it fully cured.
