Thanks, all! I didn't find anything for the 2016/2017 Volt on Ebay unfortunately. The info about paint fading and oxidation levels certainly makes sense.
Ordering pre-primed parts seems to be the best course at this point. Interestingly, both upper and lower bumper pieces include a $75 core fee, for a total of $150. It would also cost me $150 to have those parts delivered, so presumably it would cost me $150 to recover my $150 core fee. ;-)
I think I may just have a local body shop order the parts as well. I'll know when I get a few estimates.
