My 1935 pickup has many layers of paint on it. I have stripped and sanded to where everything is smooth and ready to paint. Parts of the panels are bare, some retain some of the original paint, and some have rust converter on it. I plan on painting with acrylic enamel, perhaps centrion {sp?}. I am looking for a primer that will cover all these surfaces and be suitable for acrylic enamel paint. What are my options?
