I have a TE-S and just ordered art and plexi glass by Art-Hobbies. I see many people tear off old art, is it mandatory? Can I just put my new art and plexi on top and screw it in?
TE-S stock artwork is basically laminate held on by double sticky back tape. You can put your new art over the top of it, but the plexi will stick up further than it has to. You can non-destructively remove the art already on there, stash it for another day, and put your art + new plexi on the bare metal.
