Hi

I'm currently restoring a Serie IIA 1964. I'm at the engine step and now I have the engine in parts. I would like to do paint job on the engine and I need some advice from people having experience.

1 - What is the best : painting pieces separately (Block, head, timing chain cover ) when they are separated or waiting to put all together and paint in single step

2 - The engine is currently really dirty with oil and sand. It is clear that it need a real good cleaning before painting. Do I need to do sandblast or just good cleaning with solvent maybe good

3 - This engine was originally green. Is someone has original color code for this paint?

4 - Is someone has advice on paint to use or not to use.

Thank you
