ah mate i was getting a high prevelance of wrinkles when i started but none now. How i like to attach is i like you roll the piece on bit by bit. Once the hairline is on i pull at my piece lightly so its being attached completely flat. Because when you try and pull out a wrinkle when its attached for me anyway it losens out the bond and thats no good! So yeaaaah just reattach if its really bugging you .
