In reading up on some older threads, it has been stated that the Fan Shroud & Transmission Cases are Magnesium.
I have the shroud out for media blasting along with the engine tin etc.... Once completed should the shroud be finished with a high heat clear paint such as a Krylon that is rated up to 600 degrees. Also should there be any type of prep done between these steps. I want it to look right, but do not know if they were coated from the factory or should be left in the original finish. On that note the transmission case will not be blasted, but it was suggested that it be cleaned up with a wire brush and steel wool. Is that the correct way to go and similar to the shroud does it require a clear painted finish or just leave it alone. Here is a pic of a small section that I went over with steel wool after degreasing. Lastly, once the Muffler is blasted, does that require a high heat ceramic coating? If I do not coat it, will that just accelerate any future surface corrosion? Don't really want to spend 1/2 the value of a new muffler heat coating the old one. Any advice? |

I cannot speak to the shroud as I do not know what they left the factory with, but the case for the trans had Tectyl coating on it. It was a corrosion preventative, but it wore off in a few months from what I have read/been told. I have never bought any or reapplied it. The product that many like is called Gibbs, I don't have a link available currently. It last longer. However, from my personal experience on the rare occasion that I do clean and paint a case, I just used good quality spray paint of what ever desired color and finish I wanted and it has been fine. The key is that you do want to protect the trans case, particularly if you are anywhere there is salt, or wet environments. I am originally from San Diego and lived in PA and OH and the East coast stuff is way more corroded than the West coast on average.

Thanks Doc, forgot to mention that the car upon completion will be a bit of a garage Queen. She won't come out in the rain...ever and hope not to have to drive through any puddles.
