today i removed the cam cover because of several paint bubbling spots,i used paint remover 3x to finally get all the paint off for a inspection of what i had to work with.Several of the coil wells were pitted and only a few spots of paint were bubbled.i was going to paint the cover,but gave it a try with polish firdt,so far,so good,almost half way done.all by hand,me and my drill will sanding pads'i will cover it with high temp clear.the coil wells i will use high temp,non conductive varnish.since tomorrow is easter,i will do some more on monday,hopefully,tuesday will be the finish line
Looks really nice, and another member here has polished the cover and several other pieces. The only downside he said that he has to maintain the polish very regularly to keep it bright.
I can imagine that the painted coating also helped prevent long term corrosion, so that may be another issue to be aware of if you strip off all the paint.
If you find that keeping it polished is too much work, an alternative might be to get it powder coated in a "chrome like" finish, which may be surprisingly close to what the polished magnesium looks like.
Looks good on the outside. But what about the plug wells? That is where the real concern is. The plug wells have serious electrolysis corrosion. I bought a used cover off eBay that looked pretty good. But even that one had a small hole in the very bottom of the well at the rim. Filled it with JP Weld and hope it stays sealed.
Have fun with it but don't ignore the plug wells. When they corrode through it is junk.

....hence my thoughts on powder coating versus polishing.
At least when the plug/coil wells are partially flooded the corrosion of the bottom is probably slowed!
plug wells,yes,i did that today with a coat of high temp varnish, wells and on top surface,the wells did not produce any oil onto the plugs,so i guess that i am lucky
wells cleaned ,i am at the halfway point,may finish tomorrow...no rush
more light into the wells

Reason: more information
For reference, here are some links to a fellow member dfieldsend who's spent 100's of hours polishing a great deal of his engine bay... and his wheels too:
well,i coated the cover with,"eastwood metal protect",i did not like the dull end result that it left on the cover,but,this began as a preventative maintenance exercise,also there was a lot of pitting that could not be removed,maybe a little later,i will use heavy krinkle red or black paint,,friday i will cover the coil pack cover with red carbon fiber wrap and se how that combo looks..
