Recently I've been trying to build up my vintage Thundercats collection. In searching on Ebay I've noticed some figures with age spots or fungus or something. What is this?
Here's an example... http://www.ebay.com/itm/Thundercats-Pum ... 1093309288
Is this something you can wash off? Or erase? Without damaging the figure. Will this happen to all of them in time? Looks like it mostly happens with Pumyra, Lynxo, and Ben Gali, but I've seen it on Cheetarah and Tygra as well.
