Engine Paint - I use Rustolium Gloss Black with a brush on the cast iron (block, heads intake and water pump) krylon gloss black and yes primer on the steel parts. The brush tytpe Rustolium holds up well against the heat, A factory Ferrari mechanic suggested this and is what they use on some of the most expensive Ferraris. It's also very easy to touch up.
