If you're planning on transporting a lot of parts for your car that might damage or scuff things might I recommend a mover's blanket. At one point they were going for like $8 at harbor freight. I'm sure it hits that price quite often. Best thing I investing in since I constantly transport wheels/tires, jacks, stands, etc.
