It is critical to test the surface of a primered vehicle before accepting this type of job. Some paint-primered surfaces do not have an acceptable bond to wrapping vinyls and need to be sanded or painted prior to installation. Q: Should you use or require clear vinyl overlaminate for your vehicle wraps? A: Absolutely, but with one exception. Clear vinyl overlaminates protect the finished print from scuffing, weather, gasoline, and washing. Some overlaminates also provide fading protection from the sun. Finally, most installers highly prefer to wrap with a vinyl that has been overlaminated because it provides much more strength during the initial wrapping process and during the wrap removal process. The only exception to clear vinyl overlaminate would be for perforated window film.
