So, the green light at about 20:30 - I assume that's to cure the polish that was applied just before. I'm sure there's a reason it's green but I'd like to know what that reason is if you or anyone else knows. Are they lasers or just green lights? Is green the color needed to activate the polish so it hardens? (a bit like UV light does with 3d resin prints)- I'm curious if anyone knows. Love these sort of vids. Nice work, you've got a new like/sub :D 29:20 those wheels aren't even turning, that's gotta be bad for the rail. but hey- I'm sure they know what they're doing better than me and my keyboard do :P
