Something like 15-20 years ago I bought a 1/18 scale P-47D “Ultimate Soldier” toy. This line of large scale accurate fighter planes was sort of peak Golden Age Of Toys For Adults, even though they sold for a reasonable price at WalMart. They make great display pieces even without structural modifications or repainting, but they are generally screaming for such.
Anyway, the P-47D spent years on a shelf in my shop in Utah. From time to time it caught direct sunlight. This discolored the paint *slightly,* but it turned the originally crystal clear canopies milky white. I’ve left them in the dark for some years to see if that would help… nope. I boiled them… nope. I nuked them, if perhaps briefly, with UV; no change. Anybody got any ideas? Why did this happen? How can it be reversed? Scrubbing has shown that this is not a surface feature, but seems to be throughout the plastic.
At some point, recasting them with crystal clear resin might be the only solution, but it’s not one I’m fond of. None of the other canopies did this, so it would seem these two pieces of plastic came from a bad batch.
