I've got some Magic models that obviously have symptoms, but seem to be stable and worth keeping. Zinc rot is a bummer, and everyone gets bit at some point. Keep 'em flying, Doug
Thank you for taking a look and welcoming me to the forum. I used to be on here quite a but under a different name. I've drifted back to the hobby in recent weeks. We'll see where it goes...hopefully not to the discovery of more "rotting" models.

The bubbling is more likely due to improper cleaning of the wing surface, allowing contaminats to settle before painting. The bending is likely from these same contaminats causing "Powdery Rot".

It's a recently new condition. Here is a link to a similar situation already discussed on DAC about Powdery Rot affecting 1:200 models made of Aluminium. It's very interesting reading - though worrying..


See post 106 for a detailed explaination of what is Powdery Rot.
Thank you for taking a look and giving your thoughts. I was a little skeptical that it was zinc rot mainly because the paint is bubbling not cracking as I've seen on models before.

Do you think that this is an isolated incident specifically to my model or is there a possibility that it is affecting more in the run?

Thanks again for the feedback fellow members!
