This vinyl graphic serves 2 purposes.  The first is to protect the leading edge of your sliding door from stones and things that are accidently left in the door opening when it is shut.  The second is to add some flair to your van.
 
I created this vinyl graphic to exactly fit between the 2 swage lines of the sliding door and in my specific case helps to cover up the bad colour match I had when repairing the paintwork from a rattle can.
 
As with all vinyl, care is required to ensure it is applied bubble free.  Paintwork should be cleaned and then wiped down with a suitable lint free cloth.  I recommend using ispropyl alcohol for wiping down before applying the vinyl.
