Is there some sort of software I need to download?

Can someone with knowledge of this topic please share your guidance?

You need the UV map for the specific car you want to "paint". Once you have that, you can create the texture in a paint program (Photoshop or GIMP). Contact the creator of the vehicle you want to make a paint scheme for and see if they'll give or sell you the UV map.
