I've been trooping in my Anovos TK for a bit now and finally got around to trimming out all of the pieces of this TX, but need a tip or two for marking trim lines (when fitting). I tried a pencil on it but obviously that is a little harder to see on the black with lighting, so I'm seeing what everyone else did to make the lines visible?
I've seen painters tape and lines to mark it, but not sure if there was another trick. I was thinking chalk may work too but don't want to do permanent silver marker just in case the plastic has any holes.
