Crazy that this park still hasn’t learned its lesson about using unapproved materials on its rides. The good news, at least, is that bad paint isn’t an unsolvable problem. A new paint job isn’t cheap, but it’s a lot less expensive than demolishing a massive coaster and having to replace it. Sometimes you just have to pony up the money and invest in correcting a sunk-cost mistake.
Plus, since the paint issue is limited to the running rails, that would limit the scope and the cost compared to the full repaint they just did.
