Jules,
That old 'JOE vehicle on pg. 51 just goes to show that the designers at Hasbro in the 1980s were waaay ahead of their time. Most if not all of those vehicle designs still hold up to today's standards! Your paint job is just fantastic. I especially like the fact that you painted the inside of the wheels to make it look like it had some sort of "rims" on it.
Concerning the Dune vehicle; I'd have to agree with the others, as odd a shape as that I don't know if I'd do anything other than give it some weathering. I've never seen Dune. I remember hearing about it. Anybody know if it was any good?
