Did this just once, trying to BMF a '57 Chrysler 300. At the time, I had little experience with BMF, and I now think I had an old sheet(that just wouldn't stick). Launched the body against the wall, stomped on it a few times for good measure, and into the trash it went. Felt so bad afterwards, I went out and bought 2 more of the same kit, but I haven't attempted to build one yet!
