WTB Fan Housing

I am not very knowledgeable in metals or their finishes. That said, the new fan housing I received does not have any finish I can notice. My plan is to paint the housing.
I will weigh my two fan housings. The "new" one is new this year, and I assume the old one is original, but I've only owned the car since late 2012.

I would be interested in knowing if they are now aluminum or not. If the sliver one weighs about 30% more than we will know.
Thx.

99310666703 still comes up as a valid part number. I have heard many parts are coming from classic division without previously supplied coatings or painted. Would be interesting to know for sure.

I weighed my old, presumably but not guaranteed, original fan housing at 1954 grams, while my new one received this year measured a similar 1893 grams.
Given the (low) quality appearance of the casting and machining, this seems like a believable part-to-part variation for two pieces in the same metal.

I recommend media blasting and painting or clear coating this before installing. Unless this part was preserved in some way it will need a cleaning prior to painting. Some form of media blasting followed by coating within an hour or so of the cleaning is the recommended approach.
Ideally a chemical conversion like Dow 7 should be performed prior to painting but that would be too involved.

I don't have a media blasting setup, so that is a bit of an obstacle. What's next best? Self-etching primer?
I do have a shop nearby that does Dow 7. If I went that route, would you still recommend media blasting first? After the Dow 7, is a primer recommended or does the Dow 7 act as the primer?

A good primer followed by paint would work best
