Raw Maple neck finish question

[Eruption]

I have a newly acquired maple neck/fretboard. I want to finish it/seal it before installing on a guitar. What is the recommended method of finishing a maple fretboard and neck?

I own a Universe UV777GR with maple fretboard and would like the finish to be similar.

Is it standard polyurethane that you would use on a wood floor? Is a clear lacquer?

thanks,

nelsonite is what is used commercially to seal the necks....

Nelsonite appears to be some sort of wood sealer, correct?

I'm wondering about the shiny lacquer/polyurethane finish that protects the fretboard/neck/headstock.

Can you use Nelsonite before a poly coat?

I want to do this correctly the first time and have no "oops" moments while finishing the neck.
