Looking for a "break in" oil

[mofosheee]

Yes, on the Nason. That's not engine paint, though. I used it to paint my motorcycle frame and related bits.

For engine painting, I'd use Cerakote. I'm not certain which version is best. They have lots of high temp paints, both catalyzed and air dry.

I'm going to look into the Cerekote. I had a problem with powder coat on a project where the powder would not stick to the brazed repair areas. The guy who painted my Norton cylinders used an aviation grade, UK sourced engine paint. Highly toxic, expensive and impervious to anything that the world would throw at it. Wish I could obtain about a quart for a small project. Going to look at Brownell's for what they have.

John Deere Dealers stock what they call break in oil to use with freshly rebuilt engines. I am not by any means an expert on oil. It was what I used on my last rebuilt engine. Don’t know what is in it , but it is supposed non detergent oil. May be worth looking at. It was the only non detergent oil I could find.

IIRC Deere breakin oil is 10wt, and doesn’t contain any antifriction additives. This is to allow the rings to “seat” quickly under lighter loads. They had a problem when they first came out with their premium oil ‘Plus50’ of engines not seating the rings and the engines would have high oil consumption. I don’t believe they recommended it for an engine in heavy load or high ambient temperatures.

Cerakote is the real deal. I wish I knew about them before using VHT rattle can on my KZ750 engine.

I used Gunkote on some random parts and brake calipers. It's reputed to be very chemical resistant, and tough. Sadly, though, there is some peeling on my brake calipers. Going to redo them with Cerakote, as soon as motivation strikes...

POR15 also makes some incredible paints for aluminum, as well as high temperature use.

I used their Glisten PC clearcoat on all the cast and polished aluminum on my 427 Ford, and it's held up great over the last 24 years.
It resists gasoline and most other chemicals, and has a nice smooth finish that's easy to wipe clean.
Cast iron parts got a coat of original POR15, and a topcoat of their engine enamel, which has also held up great.

Follow their instructions for whatever you're using and I think you'll like the results.
