We need to install some letters on a press box of a local school stadium. the press box is vertical corrogated metal like you would see on a metal building. My question for you that have done this is how have you set up your spacing and/or stretching the width of the letters on the computer so the letters dont look bunched up and skinny when you apply it in the ridges. and also how are you installing this? Should I be putting it all down on the outside most part of the metal then cutting the app tape between each letter and burnishing the letters down in each corogation?
