I searched & didn't see any other posts for this stuff, but I'm sure most of your already know about it.  Santa brought a jar of this for Frank.  So far, this stuff is great.  Wire brushed the loose rust/dirt off several items under the hood that are cast iron.  Buffs up to a nice finish - not supposed to discolor under heat.  Specifically made for exhaust manifolds.  Heat cures it.  I'll let you know how it lasts

It does work good. After about a year, a little touch up and it looks great again. I did my rusty master cylinder with it also. That little can goes a long way, too.

I have some and use it and am real happy with the product.  The big thing is cleaning the cast iron.

Heres a pic from an ebay seller that shows a before and after pic.

I heard(and seen) that it burns off fairly easily, apparently if not cured properly. I've never used it meself, but folks that have don't recommend using the engine exhaust to cure it. Most say it works best if you put the manifolds in an oven to cure the dressing....Mama might have something to say about that, so you'll have to do it while she is out of town...or something...

I have used it for years.  The instructions say to wire brush, then rub on and buff.  Then let the engine run long enough to reach operating temperature, shut off and let completely cool.  It is now cured.

I did our cut-away car 12 years ago.  It gets rained on and abused, and is ready for touch up now.

I use the stuff all the time. If your manifolds are rusty, you will need to wire brush them 1st. Make sure the manifold is cool to the touch.  Then take a soft cloth (put on latex gloves 1st) dab some on and work it into the pores of the cast iron. I got mine from Eastwood.com
