if it's not too deep you can probably buff it out. it won't be as easy if you don't have a buffer.
meguiar's (SP) makes some good products. they're a little more expensive generally than zaino for some of their more top-shelf stuff, but they do a damn good job. 3m also makes good buffing and polishing materials, but i've never used 3m without a buffer. actually, if you do have access to a buffer, i'd probably suggest 3m. you'll have to go probably to a paint store or auto body supply shop to get it, the local o'reilly's won't have it.
although if you want really expensive car wax, go for the zymol estate wax
