So does anyone have an NOS shroud or pic of one?
Im of the opinion that they may have been yellow Zinc plated originally, much like a good number of fasteners used on the 914.
Ive recently started refinishing a couple or three, and on the ones that had undercoating applied ... back in the day, removal of that black layer of rubberized
crap shows a nice shiny Yellow surface.

Watched this for a bit.

Rich,

All I can say is that my '72, which I am the original owner of, has a shroud that is not yellow zinc played. May have been zinc treated, but it was clear.

I suspect that the the undercoating you removed may have stained the original finish since it was tar based. MO

Cosmoline..it was on the tranny and the engine bar too...
I think Paterek knows where to get some...
(damn I have not been on this in a few years)..

Cosmoline or like anoline, a light spray of some kind of yellow gold wax. I have used CRC marine corrosion inhibitor, is similar, but putting on as much as you'd want it comes out very gold, maybe too much so.
