I can't see the bottom edge scuff but, being on edge of body, nothin' major to its resonation
Apart from that, if you don't fear to experiment (the body is almost unfinished) softly try to remove the "white" with - I dunno - a bit of nails or even somethin' slightly pointy
If you succeed in removin' it, don't worry about the scuff
Buy a Planet Waves (d'Addario group) lemon oil and polishin' cloths then act all over bass body.
If you don't put too much of it on the bass surface, you can just let it dry out in a few minutes, otherwise use a clean microfiber cloth to remove any exceedin' trace of humid oil
You can do the same for fingerboard... Pay no attention to maple fingerboard on Planet Waves lemon oil cover, 'cause maple fingerboard are always treated with something, never open pore, so it's silly how they even considered to picture maple fingerboards as to suggest you could eventually apply oil on them.
Furthermore your neck can be wenge and possibly your board as well (or rosewood) so they're open pore and there you go.
If you prefer to keep it in the family (yeah, I love old school thrash metal so are Anthrax) and stay d'Addario, you can adopt a set of 45-130 XLs or go Rotosound swing 66 same gauge
Great bass my friend,
enjoy
Cheers,
Wallace
