Re: Oxidised Engine Aluminium
Alu' corrodes the same as anything else. Just more slowly and without going orange.
Some alloy parts (e.g. wheel rims) are lacquered but this isn't completely durable and the heat may affect the top coat of lacquer on an engine..
Also the heat tends to dry off any temporary protection offered by metal cleaners such as Solvole Autosol.
Wire wool is good to clean alloy and a wire brush on the end of a flexible drill bit extenstion may be a good way to reach any difficult areas.. but really there's no way to keep unpainted/unlacquered alloy from tarnishing, except smearng the engine in oil.
No bullets for Chaingun..
