A beautiful car Tony.
I note that your rocker panels are body colour. I ran past the group last month the question of the correct colour pattern (my car is the same colour as yours, and had body colour rocker panels) and I received a number of very helpful replies, including the following from Achim:
"Definitely all pagodas had satin-black (or very dark grey - I'll try to find out soon!) rocker panels. The satin-black color goes on top of the Body Schutz (Steinschlagschutz - gravel protection paint). Certainly the detachable rocker panels were not factory-painted with body color as they were mounted separately. If you find traces of body paint on the rocker panels, this is certainly of one of the several resprays that most of our cars have had throughout their life.
The wheel houses were factory-painted with body protection (Schutz) as well and then oversprayed in body color.
I am still not absolutely sure about the trunk.
It seems to be pretty clear the the trunk of the 280 SL was painted in a very dark grey ("Tiefdunkelgrau" (deep dark grey), RAL 7164 or something like that. Hans Strom knows the correct paint number.
However, this color is not correct for the 230 SLs, at least not the earlier ones. Those (like mine) were clearly and absolutely sure painted in satin-black.
I'll try to get some more info on this soon."
It's still a personal preference thing, but if your car is a work in progress it's worth a thought. I went to original spec., and am happy with the result.
Cheers,
kns.
