Anyone have experience painting plastics?

[Omlett]

Just wondering if someone can tell me if im on the right track. I dont want feedback from a video you just watched, I want to know if you have had experience with this sort of thing and can help me out a bit.

Clean all parts with alcohol so no oil from my hands get on it

Start by doing 2 coats of a primer 3 minutes apart (probably adhesion promoter)

Spray on the first coat (lightly) of a color, wait 15 minutes
spray on second coat (lightly) of same color, wait 15 minutes
spray on last coat a little thicker but not thick enough to drip wait 15 minutes

Spray on second color with the same method as before

15 minutes after the second color drys spray on 3 coats of clear coat

Wait 24 hours for it to dry completely than put controller back together.
