Problem is it's magnesium, if you don't coat it it will look like shit in about a month.
Some guys blast it clean (fine glass, walnut or soda) and then clear it with a semi-gloss clear or just spray it with Gibbs penetrant, wax, etc.

With the gibbs or wax you will have to reapply often.


In a /6 you barely see all except the very top edge, I wouldn't obsess over it. I just painted mine close to the natural colour.

What is an alternator support? Are you referring to the fan housing?

Two fans and housings I did.

1. Media blast.
2. Sand with maroon scotchbrite pads to smooth texture.
3. Clean, clean, clean, just like any good paint prep.
4. Rattle can satin clear (I don't like semi-gloss).

On the green 911 engine I also removed the center hub and had it replated, then reinstalled with OE rivets. But you don't see the fan in a 914, so you may choose to skip that OCD step. (IMG:style_emoticons/default/wink.gif)

Thanks Mark....Good thought...I am too impatient to be too OCD but I always like to see it as you and raynekat did his....
I noticed it is hard to get strap out with scratching so trying to also figure how to treat that and then have shop reinstall without ruining the finish
What is correct?

I just had mine yellow zinc plated. But, yes the installation method leaves a lot to be desired. But there's no other way, so you just have to try your best. Masking tape on the surface may help.

Have it plated and then reinstall. I use some very thin flat strips of plastic with some lube to sandwich the strap and a plastic body tool. The strap pulls through easily without scratching.
