Just updating this thread.
All the blued Gun Kote pieces out in the weather are still nice and blue. I think it is a great coating to keep metals from corroding, much better than a paint.

The coated pistons, I have no idea if the coating wore. Engine still runs fine and has no piston slapping that I can hear. This may remain a mystery forever, I have no plans to pull them out again.

Real long term immersion in E10 gasoline, don't trust it to not maybe dissolve. Some of the coating came off the inside of the fuel bowl. Some stayed on. Dont coat soldered brass floats. I had one leak likely due to the heat melting the solder creating a tiny gap somewhere.

What is the expected temperature inside the cylinder of your diesel engine. I wold expect you are at least bumping the limits of the Gun Kote.

Thanks
Ken

Piston skirts run very much cooler than piston tops.
Consider oil burns over 300*F.

Do you have any experience or info on expected life on a piston skirt?

Just what others said on various forums.
Piston skirt coating is a legitimate usage supposedly, and there are other companies selling similar things. This was just an experiment to see what would happen. Since the skirts were a little looser that I liked. I am glad the engine does not piston slap.
