H2 Ninja Lacquer Peeling and Bubbling

I think it’s a known issue on some of the older models.

Having paint peel on edges of tail pieces and the small fins in the front fairings.

It's fungus attacking the paint, I have the same problem. Would seem that the insect impact is driving the fungus into the lacquer and the fungus is feeding on the paint, see how it expands from the original point?
