The first time I went through a car wash after purchasing mine the fuel door was open. I did some searching but found nothing that looked good for me so I keep a roll of blue painters tape under my rear seat. When I know I'm going to go wash, I put a small piece on there, maybe a couple...
That looks great. Do you happen to have 1 more pic of where it runs along the tailgate? Just trying to see how you ended each end so that when I do it myself I'm a little prepared and don't have to guess as much.
