I decided to polish my spark plug cover because it was boring and the paint was blistered, here's some pics and the grits I used:

1. 150 grit drill bit type with a fast drill to get to paint off
2. 300 grit by hand
3. 600 grit by hand and with a wooden sanding tool I made
4. 1200 grit by hand and wood

Each grit from 600 up takes about 30min and I've invested 4 hours so far (mostly looking for tools).

Next:
5. 2000 grit
6. and 7. two types of drill cloth polishers with some polishing wax stuff
8. hand polish


Just started, testing the tools


No more paint on the larger area


Beginning to look good...


After the 1200 grit
The area around the left two bolts is still in the 150 grit stage
The part with the spark numbers will be sprayed black (hot surfaces paint) because I'm just too lazy to play around with sanding the numbers carefully just to see this hidden under the black air duct.

Will update
---------------------------------

5. 2000 grit
6. and 7. two types of drill cloth polishers with some polishing wax stuff
8. hand polish

Another 3 hours today (with cigarette breaks and tool searches)


2000 grit


First polish (some kind of brown wax and a drill pad thing)


Second polish (blue wax stuff, rag type drill thingamajig)


Finally where it belongs, I'll take a better pic tomorrow.

gauthier613: you're right about that, but sandblasting is very expensive locally.
I could've also had it chromed, but that's jut too easy ;)

Another product that works very well on aluminum is Neverdull and gives very good results when it's dull and you want a bright surface finish.
It's a wadding that comes in a tin and you pull off a bit and hand rub to the desired shine.

You guys have nice looking engines. Our engines here look the same shape except they are plain grey metal all over - no colours or aluminium decorative plates.

That's pretty cool. I stripped mine done and painted flat black to match everything else under the hood. I'll post some pics when I can.
