PS pump and driveline here. WIll try and post a separate thread on restoring nice (read no pitting) drivelines
Not allot of interesting stuff to take pictures of but refinished the PS pump (wish I had installed it on the engine before the engine was installed
Its painted with NPD newest PS blue. Hard to get the contrast set correctly in the picture to show the true color of the pump.
The upper end of the neck and the area behind the tag were shot with a "natural" steel paint before the blue color was applied to reduce the possibility of rusting later. Phosphated high pressure line indexing bracket can be seen at the rear of the pump
Also started to refinish the driveline today. We started with a pretty nice one so it was not that difficult. It was stripped then wire brushed and then sanded to return the surface to a fresh metal look. The using the gun bluing repair fluid the welds were darkened and the metal in the surrounding area darkened as it would be after the welding took place.
Also added the blue stripe down the length of the tube (the tube would have been formed by forming a flat section into a tube then welding it) Usually this take on the look of a darker "blue" stripe with a softer "darkened" area like the other welded areas
Finally the ends were refinished as bare cast iron with bright machined surfaces. Then everything was cleared with a stain clear.
Look for an article describing (with pictures) in another sections of this forumID stripes and such added - all done for now - on to the U joints and yoke
