INSTALLATION
Clean the application area and apply the vinyl using a WET installation. Make sure the area is clean and free of dust, debris, dirt, Armor All, etc.
Some will choose to clean the application area with rubbing alcohol which is okay.
"Rubbing alcohol will not damage car paint if it is diluted to between 10% and 15%. Since rubbing alcohol evaporates quickly, it doesn't damage car paint."
Try doing the install in the shade so it doesn't heat up the vinyl rapidly.
