I saw a similar question today on pg.com but my question is.....

How do they do the endzone at Heinz. On saturday the endzone that says "Pittsburgh" was gold outlined in blue, than less than 24 hours later, yesterday it said "Pittsburgh" in yellow outlined in black, how do they switch back and forth and make it look so clean all the time, I am intrigued by this. Do they brush the paint off then repaint? Do they just paint on top??
I remember the first year Heinz was open they actually made the whole endzone yellow and painted steelers in black in one end and pittsburgh in black in the other, than on Pitt games they made the entire endzone gold and made the fonts blue.. ...how did they do that...please someone explain how that is done so fast...

also...I do miss the old endzone from three rivers with the helmet in the corner with the steelers in one end and pittsburgh in the other with a background of yellow, very superbowl like....
