Thanks guys.
Mick, this being my first time polishing cast alloy I was really trying different things to get this result.
Firstly I washed the parts in a parts washer then blew to dry, cleaned them next with brass wire brush. This cleaned any dirt off and started to sort of polish which was good. Next I used a buff on my drill with compound for alloy. Slowly went back and forth until I was happy with the shine, adding the compound regularly. Finally finishing with a polishing cloth to get any small remaining bits of compound left in the metal. Now I know this might not be the way everyone does it but I am always open for suggestions to improve.

As for the clear coat well I will be clear coating the hardware (nuts, bolts), but I am unsure about clear coating the engine yet. This engine wont be going on a mower for some time, as I am doing this for a practice. It's just going to be a show piece for now, lol. Not going outside at all. But if anyone has any thoughts on this I'd like to know. Thanks
