I have also decided to stay with the chrome plated parts to save the effort of stripping the chrome and then repainting - first with a black primer and then with Alclad. It always used to be necessary because the manufacturers always put the chrome plating onto black sprues so any cut points always showed and it was almost impossible to hide them. Nowadays, the chrome is plated onto white sprues leaving the tiny cut marks almost imperceptible.
So the first step was to build the engine. I am painting the car in Tamiya metallic blue so I used that on the engine block.
