Overall I must admit I am not an expert at installing these, but I am installed a lot of stickers. I wet down everything really well and even playing with the placement for 20 minutes, I could not get it to fit without creases in the center. I finally used a heat gun, and I got it a little better using that. I did have to finally settle for some imperfections, but its not bad. Should help out a lot with the sand blasting that occurs in my area.
