Metal Cabinet - Paint to use?

Hey guys,
I have a big metal cabinet that I used for my first grow, covered with emergency blanket material. It worked okay, but a few tears happened after I moved around my reflector and I'm sick of fixing it. So I was wondering, what kind of paint I need to paint on top the metal? I know I need flat matte white, but I mean I'm sure regular paint will just peel off metal, so what would be a better option?
Thanks in advance for any help!

its called dtm in any proffesional paint store.direct to metal.PEACE

Enamel Paint would be ideal. It can handle the heat and very durable. Make sure everything is clean when you start.
