I'm stripping the 2-3 layers of paint (orange, silver, and red) off the Global 1/2 VW I'm close to assembling for the Hummelbird I'm building, and wondering what needs paint and what doesn't. The cylinders are steel, so I know I need to paint them. Cylinder heads and valve covers are aluminum, the whole engine weighed 85 lbs, not sure if the block is aluminum or magnesium. Do any of those need to be painted, and is there a recommended paint? I seem to recall Pops stating the valve covers should be painted black to help with heat dissipation, I assume black paint on the cylinders would be good too? I have a can of VHT black engine enamel which is rated for 550 degrees, is that good enough? Should I use primer, or will the paint be fine as is?

I'm not building a show plane, so basic protection is good enough for me.
