Post a pic of what you're working with. Do you know if its Single Stage paint or a Base Coat - Clear coat type paint? How old is the paint on the vehicle now? Do you know how much paint is on it? How many coats?

What color is it? Is it metallic paint?

Not trying to be a smart ass, I am genuinely trying to help you out but it all matters as to what you should use on it. If its Single stage paint (just a color paint that shines when it dries) or a 2 stage (spray a base color, then clear over the top) if its metallic (glistens in the sun) and its several years old, clear coat is faded, etc it will be very easy to burn through to the base coat as you're buffing.

As others have mentioned rotary buffers can be helpful but they will also ruin a paint job quickly if you dont know what you're doing. Be very careful along the edges, body lines, where one panel meets another, etc. As the rotary buffer spins you want to work off the leading edge, dont sit the buffer flat on the panel or it will "catch" the edge as it spins. Hard to explain,.. Imagine a circle spinning over the seam where the hood meets the fender. As the circle (direction) comes OFF the edge, theres minimal chance of it catching.. but as it spins back ON that same edge / seam it will bite into the edge.

Post up some pics and I'll make some suggestions. Is it just faded or is it orange peel you're trying to get out? Imagine the skin of an orange.. when a the last time you've seen a shiney orange? It's because the surface isnt flat. Same for your paint. Its has to be flat first, before it will shine.

Happy to help.
Later..
