undercoat what has been done originally in '69..?

[Bart de Bruijn]

Hi out there!

Now I almost finished all the welding of the chassis on my 911T '69. It's time to prepare the next step.
Parts of the chassis have been sanded back to bare metal and then sprayed with 2 component epoxy primer. My question is what is originally done....
after this epoxyprimer first a layer of rubberized underseal (stoneguard) from Wurth. Should this undercoat been sprayed in the original body collor (Bright Ivory) of the car? Or should the whole floor pan and and wheel arches be black? I looked into a lot of books, but I could not find the answer....

So what is the best way preserving this long term restoration project and/or what has been done originally in '69? All advice is more then welcome.

A 69'er should have all of the following in black

Wheel arch,
Floor pan,
front trunk, and
the engine bay

The original coating was a (petrolium) based product some say Tectyle

I think the standard used now is Wurth SKS, although i've seen some people use Wurth sprayable sealer.

My car is an Australian/Euro spec 69T and was pretty much untouched before i started it's resto
