S!
Gripens I assume Petter
North or south? We do also paint the interior of the cockpit if required because the black paint is partially anti-glare and also prevents from white light coming thru the panels(not all are metal) thus would interfere with NVG. So imperative to keep the cockpit paint in check. This applies to the exterior and equipment bays as well, if left unpainted corrosion can hit pretty fast, and that is not what you want
Anyways. In the screenshot paint has chipped like it was badly applied. I think most areas that would be worn are around the attachment bolts of the intrument panel etc. But again these were war machines, not civilian cruisers and in the heat of the battle small details like chipped paint could slip thru and manpower focused on keeping the plane combat ready and air worthy.
