I am not sure if it will show. but all the talk lately about salt on roads and east coast vehicles. I lived out west and I knew they used salt on the roads so after some research I found that alot of States use salt maybe not to the extent as New York! but it is still salt My sisters car in Florida was never up north and she washed it alot but still rusted under all the Plastic from salt that was on the top and ran under the plastic from washing
