Hello all. Hope i can get some clarification here and put my mind at rest. i have a new 4 motion tdi 400 in black. I also have dual sliding doors, now i have noticed 2 parallel lines (high points) in both sliding doors, very slight but still noticeable from a sharp angle. The lines correspond to the adhesive lines on the back of the skin where it meets the channel behind (this is on the top half of the sliding door and runs vertical down the middle). I have also stuck protection panels (birchwood from modexion on with double sided tape) using pressure only on the middle channel and surround and not on the actual skin, my worry is that i may have caused this while others say its the adhesive used in production. Could someone give me some of there opinions? Thanks in advance.
