Did the 928 come from the factory with air horns?

I'm sure your painter is aware that he'll want to apply a similar treatment to the exterior metal as part of the refinishing process. Proper bare-metal prep is particularly important on the aluminum body parts like doors, hood, and front fenders. Your work will include a modern paint system so all can be easily considered in the prep and base layers. The original paint systems, particularly for the Glasurit single-stage solid colors, needed extra steps to work with the then-new-technology aluminum and polyurethane body materials.

Lots of work, but the finished product will be wonderful. It's pretty amazing that the cars were originally assembled and finished in such a short time at the factory. What takes me weeks to do myself took them minutes to maybe hours.

Thanks for sharing the pictures and descriptions!

Thank you for the information.

One more reason for taking the car back to bare metal was that the original base primer started to let go from the metal/galvanisation with small bubbling occuring. Also with both the original Moccaschwartz and the red metallic color on top made it very thick so adding another coat would not be a good option.
With too many layers the edges on the different panels will be to "round" and not look good.
We will use a modern 2 component Glasurit paint without clearcoat. Reason for choosing to exclude clearcoat is that it will be too shiny with it in a way that these cars did not look from factory with the solid paints.
The painter is a very experienced professional and I am confident he will use the proper products for the given materials.

Sounds like your guy is trying to get the car 'just right' -- can't wait to see it!!
