    I picked up a spare set of manifold covers and was wondering if anyone has suggestions on the best way to bring them back to life and make them look good. They are pretty crappy looking right now - but have not cracks. The studs will probably need to be replaced as well. So what can you do with magnesium covers?

    This has been asked before (search on Dino cam cover). My response was as follows:

    I know that the 206GT and early 246GT cars have magnesium cam covers and they were treated with DOW 7 chromate conversion coating which gives them their greenish-grey color. If your covers are indeed magnesium, find a local company who can recoat them. I live in the Seattle area and Protective Coatings Inc. (www.potectivecoatingsinc.com) did mine when I restored my Dino in 1999. Given the use of magnesium products in the aviation industry (and Seattle=Boeing), these guys have lots of experience with DOW7 and they did a good job. Don't expect them to look like jewelery when they are done, they'll just look right.
