Painting my old USPS mail truck with Rustoleum (and no experience)

Part 1:    • Restoring a Grumman LLV Mail Truck.  It's ...   The rare, exquisite, gruelingly slow-moving beauty of the Grumman LLV. No less subject to the punishing passage of time than you or I, the paint on this was some of the worst I've ever seen. Fortunately, being made of aluminum, this didn't leave any structural damage, and is nothing some sanding and fresh paint can't restore. I managed this on a shoestring paint budget of just $100 and a few weeks of elbow grease. Let me know what you think! There were plenty of mistakes and learning opportunities along the way, so please comment if you have any tips or questions about anything at all!
