I didn't on my FlashForge CreatorPro unless I had an issue, but I do on my BambuLab X1C - but that's because it's a fully automated process using the built in lidar.

I would contact their customer support, it's likely they'll send you a new roll, and hopefully it will help them improve quality knowing they shipped some bad ones.

I use the spray cans, and it just takes some practice. If the result isn't good you can wipe it off and try again. It's not an easy skill to master at all.

I use Manjaro, but I run it like vanilla Arch (for example pacman/yay and not pamac). I find this to be a sweet spot for me - rolling releases are so incredibly nice, and Manjaro being slightly slower than Arch is good from a stability standpoint in my experience.

I use ZFS all over the place, including the root storage pool on my home server, which has overall been a great experience with systemd-boot.
