Default Inflight Hawaiian DC8 Zinc Rot?

Sorting out models to sell and the Hawaii DC8 Gen.1 looks like the wing has zinc rot? Model is 14 years old.

My other DC8s an early Balair and Alitalia are fine.

Only the dark grey is affected ... maybe something wrong with the dark grey painting ?

Doesn't look like zinc rot, just poor paint prep. Looks worse when enlarged in photo, probably not as bad in person/displayed.

I also believe it has to do with the paint mixture or the base primer undercoat, all my early Gemini 200 757-200 models have this same bubbling of the paint.. very strange indeed..

I agree with others, looks like a paint issue to me.

I think it's a paint issue too. Zinc rot is usually the paint peeling off and then the metal itself disintegrating. I have a few models where the paint has bubbled and doesn't go any further than that.

This thread is about an Inflight model, however... there is this thread that may or may not suggest the G200 fuselage is aluminium but other parts of the model perhaps wings and pylons are zinc alloy.

I dont think its Zinc rot, most of my JC wings models have small bubbles under the paint. I do believe it could still be some sort of corrosion which is causing bubbles in the paint, however if so its not aggressive like zinc rot. Looking back at photos of some of my models these bubbles haven't noticeably progressed.

In fact on some surfaces (non-metallic colour with no printing), you can use some fine grit sand paper to sand them down and then polish it, completely removes the bubbles, like they were never there. Just be careful of printing though

If thats not an option then you can also hide them by applying several coast of a hobby grade clear acrylic paint, then carefully sanding/polishing it. This works well over any surface of the model including printing, however you must be very careful not to sand too much off. You can apply a few coats, sand, apply a few more coats, sand some more, ect, to make sure you dont 'break though' and start sanding the tampo printing. Make sure to use fine sandpaper, also polishing sticks for fingernails also work well. This will even up the surface. But the finish will look slightly different, so only do it if bubbles are obvious

Hope this helps

You know what they say... don't buy diecasts as an investment Perhaps Hornby shares would be better for your pension fund... then again perhaps not
