Paint Exceptions And Associated Repair Procedures (G1676685): CISSING: Description
WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
Cissing is identified by the presence of small crater-like depressions in the paint finish, which may vary in size and depth according to cause, from individual craters of pin-hole size in densely packed groups to isolated craters of up to 10 mm (0.4 in.) in diameter.
Craters will often reveal small impurities at base when inspected with a low-powered lens. The exception may be uniform and densely arrayed but in most cases occurs as individual fish eye type craters.
