Rust oleum spray paint vs Wagner Flexio paint sprayer

[Aarondowns22]

So I’m sure this has been discussed a million times so please forgive me. I have a stock white RXV 2013. I’d like to paint the body black. Would I be better off using the rustoleum spray paint followed by the clear coat spray paint, or should I use the flexio paint sprayer? If the paint sprayer, how would I go about getting the clear coat? Also, with either of these options, is it really that simple as to spray the paint on then the clear coat? Thanks so much.
