Question for the group. I'm new to building and after a looooong wait, I just received my first kit yesterday from Vans! I am very excited to get going! I'm inventorying my tail kit and I'm finding a lot of parts that are obviously pre-owned. Many parts don't have the blue plastic film, some have already been partially deburred and I've even found some that are partially dimpled. I feel like I bought a used kit Is this normal?
