That's quite a bit of work to get those results - well done!
As mentioned by others, definitely apply some type of clear coat or the aluminum will oxidize to a dull grey colour after just a few months.

Yep it was a lot of work to get it all clean and shiny.
Pulling the motor for a rebuild sure helped as did about a gallon of de-greaser, many hours with a wire brush and 3000 psi sprayer. A bunch of new parts didn't hurt either.
The spider took many hours, as did polishing the center brace, fuel dampers, fuel lines, water bridge, about anything that would look good shiny.
The car is sold now, off to a good home on the East Coast. It took quite a few months to find someone who would pay what I thought the car was worth.
Not even what I had in it in cash and man hours, but a fair price that very few on this site would have ever thought an OB would bring.

Looks fantastic. But the amount of effort to get it that way and maintain it is a life long battle. If and when the clear coat goes bad, you have another mess. So what about sending the intake out to be ceramic coated similar to a set of headers??? Is this a possibility???
Very durable, bright and shiny, and no sweat!!

that all looks awesome! nice work.... I did mine on the part euro 5 liter but got impatient and just took the flat spinner sand paper w drill and went over it all. actually the plennum looked like a mirro but lots of swirl marks . with the painted porsche emblem, it looked awesome... i thought. not as nice as you guys did , but still very nice compared to stock or stock dirty.

I spent many hours grinding the corners of the center plenum and removing the cast-in ribs from the parting line and other raised features. Once I finished I sent them to a local polisher who made them look pretty for under $400. Well worth it in my opinion as it would have taken me forever...
I had this done probably close to 4 years ago now and they are still nice and shiny. However, I stalled out on finishing the rebuild and it's just been sitting for the last three years in my shop...
I should probably remove them and have them coated before I start driving it again whenever that day comes.
