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? |
