Can you paint a fire door?

I've found that the best thing to do is get it laminated. All paints fade and don't look new after a while but getting it laminated keeps it looking shiny and new! A few years ago I got mine done fairly cheap from a company called Excelsiordirect (they have a website explaining in better detail, I'm not really a pro when it comes to this sorta stuff!) but i do know that it looks loads better laminated than painted, and it still looks good as new :)
