Thank you very much, have just tracked down description of film & it is the one, will try hunting down a copy now, thanks again:)

I'm looking for the title to an old sci-fi flick about this boy who find an object in the junkyard, and puts it on his head.. gets wrapped up in this crazy alien suit of armor, and saves a few people... any help??
