I painted the lower half of mine about 15 years ago. I washed it down with wax and grease remover first. Then I scuffed the factory painted aluminum with 3M maroon scuff pads. Around the moldings where the scuff pad didn't work well I used a stainless steel wire brush. Painted it with my old Binks no.7 paint gun outdoors On a calm day with DuPont acrylic automotive enamel with a catalyst. Paint is still on it and it has been outdoors since. If you can do a search there was a fellow several years past that painted his Corvair with a foam roller and Rustoleum. it came out very nice.
