Be careful, Newark used a treatment on several aircraft [Buccaneer and Lightning both come to mind]. OK in the short-term but over longer periods it can be a nightmare; the surface eventually crazed and split, despite it supposedly being UV stabilised.
I believe that the issues with the Buccaneer were resolved [slowly] during the recent repaint but the Lightning still has to be addressed. You could check with them to see which product they used http://www.newarkairmuseum.org/contact.htm
