I'm no chemist, but how can something be "impervious to every solvent in the world"?  It has to have a base, right?  Water-based, oil-based, whatever..... there has to be *something* that'll reduce it, right?  And if the "price is right at $34 a pint" more power to you guys.    If I was building a model to go in a museum and someone else was picking up the tab, that price might be right, but.....  Geez......
