what's the proper undercoating for a 914-6? Options

[siverson]

I tried extending a thread on the originality forum, but not much luck there:

Anyone have photos of an original or 100% properly restored 914-6 showing the rear fender wells and bottom side of the rear trunk? It seems like black undercoating is never right as it was just applied by the dealers or ports (or something), and besides it's ugly.

So, it seems like the good options for these areas appears to be:

1. metal -> primer -> body color paint

2. metal -> primer -> grey PVC undercoating

3. metal -> primer -> grey PVC undercoating -> body color paint

Or ?

911 have the pebble finish ..914's PVC is pretty smooth with orange peel and sags here and there.

I agree, after cleaning off the black underside of my 72 - 4, this is what I found.

Wheel housing:


Floor pan:

Under body:

Paint close And the dove gray primer:
