Quoted from steigerpijp:

No its everywhere,
Im seeing what I see a lot when I get back race helmets for repair , bunching of paint Exactly like this around the visor screw Pivots
When I deliver the a new freshly painted helmet , I always say, when you change the visor, hand tighten down, that will do the trick.
Some ignore it, and because the clear Inc underlaying artwork are twisted/squeezed so hard, the bond or key with the base breaks and it flexes slowly around the pivot. Being soft this is possible, after the hardening continues, the trapped air underneath can still expand and contract, but now the paint wont flex anymore and .. chips under the stress.
So once the bond has been broken, it will never return.
I heated up the affected areas on my “Willy” with a hair dryer , and as hoped, the air expanded, you could hear the pop when it broke the seal with the paint squeezed into the paint , and then settled down flat.
After cooling it would not come up again.
Did this on 7 post that were in sight, and replaced with washers of the same diameter as the posts or slightly bigger. This helps to spread the load instead of just the starpost edge digging in.
For now this should hold up, but the deeper issue remains
