This year the official rules prohibit the use of mercury, lead shot, or anything else that is loose inside the body. The full plastic shell is in full compliance with the official rules, although, as you mention, individual troops can apply their own rules as they see fit. As it is, a lot of weight is in the shell, and it is not optimally distributed for the best speed. But it will be a great looking car!
I remember when I was a cub scout. There was big controversy if certain ppl in the troop were using mercury as a weight. The idea is that the mercury shifts as it hits the bottom of the ramp, giving it an extra oomph of propulsion.
Another thought. You may want to make that smoother for less wind resistance. Try an Acetone Vapor Bath http://www.soliforum.com/topic...
