Hi @codabat and Happy New Year 
You did good job scanning it , however if you want to scan together with textures you need to purchase another 3D spray that allows you to scan difficult objects but preserve it’s color , sadly AESUB is not that proper spray , since it is mainly used for no colors scanning .
You can try Attblime Zero , it will just frost it slightly still preserving the colors .
The problem in yours is the shine and the black parts , without slightly frosting it , it will be not possible to scan it .
What you can do else ? You can purchase Attblime ABX in a canister not a spray can , use small brush and paint with the 3D spray only the parts that are problematic to scan , this way you preserve the rest of the color and in 3D program you can easy restore the black parts by painting it back .
I hope it helps
