Yeah the "go away" paint hasn't really been working too well recently. Worked int eh old days to some extent when it was just hiding something right on the edge or backstage, but things like Guardians, Rat and this - nope.
Such a disappointment. I remember when I would take guests backstage on tours, they would be in awe that Splash Mountain or The Haunted Mansion were not actually in the mountain or house. The idea of a "show building" didn't exist to many people. Now they've lost that art completely.
