Not really but here's a rough idea
Since its already primer you can skip primering it
I would wipe it down with some diluted alcohol just to make sure there is no grease, wax etc on the primer
-spray a light coat of the color match paint allow it a few minutes to dry
-spray a second light coat and be sure that all the area that you want painted or being covered (allow enough time to dry)
-spray a medium coat (allow time to dry)
-evaluate how many more coats are needed where you're satisfied (usually I do 4-5 coats then begin wetsanding)
-start wetsanding i usually start with 800-1000 grit
-then move up to 2000 grit
-evaluate your work depending how satisfied you are if your not then go back and redo some steps
-compound/polish the wetsanding marks out. (At this point you should be have a smooth finish)
-ipa wipedown
-light clear coat (allow enough time to dry)
-spray a medium clear coat (allow enough time to dry)
-another medium clear coat (allow to dry)
-at this point it's up to you as to how much coats you want to spray, once your happy allow 2-3 days for the clear coat to dry throughly.
-wetsand again start w/ 1000 and move up to 2k
-compound/polish.. By this step you should have a near factory finish.
There's several different ways to do any type of painting what works for one person may not work for another so adjust as you need to. If its the first time your trying to paint i would grab some type of mirror, spoiler etc from the junkyard and practice on that and get your process down.
