I just went through this process on my early 1970 914-6.
Rear valance inner finish is original only re-painted out side was re-textured and re-painted.
Both my original rockers and front valance had a thin coat of texture on them; light tan color similar to 911 fuel tanks only much lighter in coverage.
The texture was duplicated with Wurth body Schutz in tan and painted with SEM satin black trim paint from a gun.
A notable difference is that the rockers have a finer texture than the valances.
Also I have an original paint rocker from a 1975 car that has no texture so it appears they changed during production undoubtedly to save money.
With the re-plated original hardware they are like new.
A lot of work to get them right but the results are stunning in person, photos don't do them justice.
