I agree, I have done the same areas as well as the heads and block too; works great.

Well, you guys are the bomb!!! Went to the store down the street, didn't have any Simple Green, but did have something call Purple Power, some industrial, bio-degradable degreaser. Scubbed with a wiire brush and wiped clean. Then buffed with some 0000 steel wool, here are the initial results. Not too bad, a couple more nights of scrubbing and I should have it done. Thanks all!!!

Hey Rich,

I might be too late, but I am slower than you and trying to juggle multiple projects with my build. I wanted to make the tired old diff and all the other components look better since I was doing a rebuild. I'm not NCRS and at the point of no return so what I did was fine wirebrush and still looks a little corroded and aged.


What I ended up doing to do the batwing and will do the case is cleaned it with POR-15 marine clean/rinse, then metal ready/rinse. The other pieces in the tunnel (shields) area are all being done too.



Then I applied 2 coats of POR-15 Stirling Silver then poly bushings. I love POR-15 and have been using it since I was in high school on my 68 Z/28 Camaro (boy I wish I still had that car.....even over my ZR-1). It came out pretty nice and it actually the same color as the aluminum when painting it on (used foam brush and fine paint brush for the detail areas). It took me a few days between the drying and tedious painting, but I'm really please with it.

I don't have my case right now as a friend is taking to his shop to remove the clips so we can rebuilt the posi before getting the 4:10s put in by a local shop. When I get it back I will do the same but the yokes will be POR-15 black. I'll post pics when I get that done and the whole deal together.

Looks great Craig!

Thanks Jeff, now if I can get it to run as good at it looks........

I think it could be blasted, but I would want to use something more gentle since mine was already a little corroded. That is why I figured I would protect and seal it since I'm way off original already.

Thanks John. I have always only used it on rusty steel (when restoring my 68 Z/28 and 49 Chevy Custom Rod) and never thought about it on aluminum. After consulting with tech at POR-15 and all the searches on the internet, I came across these guys in Australia and started consulting with them about the motorcycle engine (click on the pics to see how nice it came out) to make my decision.

Wow Craig....looks awsome!!! Can't wait to see the case. In hind sight, I wish I had hit mine with some paint too, but it came out OK.
