I was going to spray mine with Gibbs, but forgot to and now it looks not-so-great...I guess I can clean it and spray.

I have been second guessing not putting a TB Diff in it (no need for LSD since it'll be street driven) when it was rebuilt. Since it's still out I might revisit that idea. hmmmmm

Try spraying with Gibbs anyway, or try a small section. It might bring back the finish. Couldn't hurt in the meantime

Good point, worth a shot right (IMG:style_emoticons/default/biggrin.gif) My shiny billet side and intermediate plates really make the dull/dark case stand out. Let me try it and I'll post a photo when I do (IMG:style_emoticons/default/biggrin.gif)

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.

Like Boeshield T-9?

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

(IMG:style_emoticons/default/thumb3d.gif) I've just been using paste wax. 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!

When I started doing work for The Revs Institute the first thing I learned was how they relied on Boeshield to keep parts from oxidizing without coating them. Since I built the first engine for them I have been using it on every engine case. It doesn't smell, doesn't drip off, and it doesn't attract dust/ dirt as long as its applied in a proper amount.
