I'm debating on whether or not to try to do anything about the oily glue that seeps out from behind the soft black/gray material on the inside of the head's chin. Does anyone think leaving it as is, with a little bit of that stuff contacting the figure neck, will ever cause any discoloration or other damage? I understand OMG recommended using lighter fluid to remove the oily glue and putting modling tape over the soft material, but that seems like a bit of a risk too.
