I am trying to finish my notes to accompany the rebuild video (notes will be free) and I am wanting to pick your collective brains for info on corrosion prevention for the mag alloy case. What do you do? The factory coating only lasted a few years and is long gone now. On most peoples cases, it is the oil that keeps it from corroding (IMG:style_emoticons/default/wink.gif)

QUOTE(bkrantz @ Jan 17 2021, 07:39 PM)  Has anyone tried T-9? Yes. Seems to be good stuff. I used it on my fan shroud and so far it has stayed a nice factory gray look so far (about 2 years indoors). I also treated my transmission case above with it a week before daubing on the Tectyl. I think the Tectyl will provide significantly more protection, but the T-9 is invisible and doesn't leave a waxy coating if you want to avoid it. |

I can't believe I never thought about using it. Works great on my table saw and jointer. (IMG:style_emoticons/default/smile.gif) |

(IMG:style_emoticons/default/beer.gif) @bbrock Light coat, buff off, then your favorite paste wax. Works wonders. My equipment is in an unheated garage which gets warmed up just for use in the winter so condensation is always an issue and since using T-9 I've stopped having table rust issues. Edit: Make sure its really clean and relatively warm first so the propellant can evaporate in a timely fashion-or I've seen it get a bit gummy. |

Of course that works fine but the instant indicator of when it wears is flash rust even in my low humidity world. Will be great to have that extra layer of protection soaked into the pores. Thanks for the tip! |
