What type of paint to use

[butcher_boy]

Great ones,

Part of the process for registering my school bus is that I have to paint it. It can not be school bus yellow when I register it as an rv or what ever. Does anyone have any idea on what is a good "primer" to use. and how should I spray it on? I want to have a primer that is going to cover up the yellow/orange and black colors. How much prep work do you think I should do to the bus (ie sanding ) I am thinking just a nice somewhat even simple sanding to get the primer to stick.
Any help would be great, And yes I am will end up annoying alot of you with my questions.
