Paint that oil will not affect ?

[Ken_Shea]

Looking for experienced advice here, I have a transmission housing that is made of aluminum, I want to seal the inside with paint, any one know of what type to use so the lube will not affect it ? While not automotive it does use standard differential lube. I glass blasted the interior so it could be dye checked for cracks and while I did clean it I do not want any of the media working it's way out and trashing the bearings or gears.

Thanks
Ken

Probably some type of epoxy paint.

Ken,

We used to paint the lifter galleys of our race engines with a type of paint to get the oil to slide back into the pan faster and not pick up as much heat. And to "trap" anything after we had machined the lifter bores and oil return holes and such.

It was a rust red color. But with old age and time, the name of the product slips my mind. (what's left of it.) I think it was a Rust-O-Lem product.

You might ask around at the local hot rod shop or even do search on the web for it. Maybe "engine lifter galley paint".

There are probably better products now as that was some 25 years ago.

Ger21, not sure on the epoxy, I believe it would hold up to the lube though, Epoxy makes me think thick an flaky.

I have tried the search thing Ward but nothing comes up as of yet, may call Jegs or Summit tomorrow, I am thinking some sort of chromate.


Thanks
Ken

WMS: From memory there was another product "Glyptal"

I used it for lifter galleys and internals a long while back also.

I think it was designed for electric motors (this is really giving the brain a workout here)

This is from back when I was a kid playing with Big Block Chevs and a tip I picked up from a HP book.

No thank you Ken and IJ.

That was a trip back in time, for a minute any way.

Well... back to the present.

How about using silicon. Not much touches that. It also has good sealing capabilities and withstands high temperatues. It also is flexible.

Just a thinking out of the square idea.

No Ken I havnt read the pdf yet .

Just broke out the abacus and that was 25 years ago for me !!

WOW where did that 1/4 of a centaury go?

"Rustoleum" was mentioned in my book but I could never find it for sale here in Australia at the time.

Ken,
We have aluminum parts painted that go into helicopter transmissions. The specification calls for a Epoxy Polyamide Primer (Mil-P-23377). If used on an interior surface, it does not need a topcoat.
