Is there any issue with wiping the poly over the frets? (new to this whole business)
Hi Jasper, and welcome.
I think we're presuming you have a maple neck with maple fingerboard, but you haven't specified that or whether you have a or maple neck with rosewood fingerboard.

The difference being that a maple fingerboard, yes, clear coat over the frets as Simon described. Rosewood fingerboard, no clear coat on fingerboard.

Also further to what Simon mentioned about using "tinted" clear coat, this method will provide a more even colouring as opposed to staining the neck timber.
It's not that you can't get an even finish staining, but it can be hit or miss depending on the timber itself.

And to further quote Mr Barden:
Bright yellow or orange isn't a good look for a neck!
I learnt this the hard way... not one of my better finishes, but it plays like a mofo!
