just purchased a murena 2.2 in england. Getting to know it slowly. Some one painted the panel below windscreen, looks terrible. Is this panel replacable, repairable or am I in serious trouble. What is this panel made of...
The panel below the windscreen is part of the galvanised chassis, and it should be finished with a black crackle finish paint and look like the photo Oetker posted. The problem is that Matra forgot to prepare this for painting! To paint on a galvanised surface you must first use an etch primer. Then the paint will adhere otherwise (as with all the original cars) it will crack and lift off.
So clean it all off back to the galvanised surface first. Then treat the complete area with an etch primer. Finally paint black with a crackle finish paint, similar to those used on old British car metal dashboards. We had done a car like this and it is now better than new!
