 How about purging the tank with nitrogen or carbon dioxide, then cap and
 plug the vents?  Even with a small air leak the mixture would never be
 lean enough to burn or explode.

 So is there something we need to make sure the painters do if they are
 re-painting.??
 I imagine that no painter would paint a wing with fuel in it - right?
 or do we want full fuel so there is no vapor - stupid question ??
 Other than the front strut, what, where, how, else can you ground??
 Is it as simple as no material under then plane and no dust removal
 with air?
