so does this ebay jem look melted ??

Hmm can't blame it on the lamp inside, like this one on DCC.

Back when I was writing how-to articles for magazines, I set up my photo lamps on a kitbashed model of a heavy weight pullman.

By the time I made all the camera adjustments and took the color slides, the car's side had softened and warped -- just like that ebay picture! I've had that model in a box for 30-years waiting to rebuild a new side for it out of styrene.
