Two of my main pieces were just over 1/8" short so now I have a noticeable gap. It's critical to buy rapid tac to spray on the vinyl piece and the panel so you can move and position the piece around. If not, you will NOT be able to fit it. The glue stick dries up quickly and is not worth the money since it dried up before I finished all the pieces. I paid the extra $10 for the lifetime warranty but not sure if I even needed that considering the vinyl is thin and didn't look like "lifetime quality" material.
