::edit:: Found out it was my silver paint marker---it REALLY doesn't like the blue plastic on Prime. I've used that same paint on dozens of TF's over the years, never the slightest problem. It also has no effect at all on the grey plastic. But the blue? Darn near eats it like acid. Sigh. "Pen-Touch Silver" by Sakura. On a related note--anyone know of/have a broken leader movie Prime that I could get the lower inner leg part from? It's the same in all versions AFAIK, it's just a solid piece of dark blue plastic.
