Hot dog cart signage

Hello,
I amnew to the forum. I have an aluminum hot dog cart that I bought a few years ago. I currently have a rather bland looking vinyl sign stuck to it. I really want something with eye catching appeal. Is it possible to paint a sign on aluminum? or should I stay with a vinyl adhesive sign? They say flash is cash. Any info would be great. The aluminum looks so blah and is really hard to try and put a shine on. I am definately going to try and buy another one in the future that does not use aluminum.
Thanks

I would go with a few of those magnetic signs, or get a hi speed drill and some polishing compound and bring it back to life. BUT if you use signage you could take it to you new cart. Just a thought!

get an aluminum wheel polish at your local auto parts store and then like jojo said use a buffer afterwards use a higloss clear acrylic spray paint, alternativly you could paint the cart an eyepopping orange or yellow, black vynil(sp) available at marinesupply or craft stores would contrast nicely

Thanks guys!
I'll try it out. Wish me luck
