With the engine bay thoroughly sanded, we moved on to paint. Rather than just rattle-can the bay with basic enamel paint we decided to try some of the new products from Eastwood. Our bay was nearly rust free, but we hit the areas with surface rust with the Rust Encapsulator. To use it we simply sprayed it directly over the surface rust. The encapsulator is a great product since it neutralizes the rust and keeps it from spreading.
