Using something like the Krylon that is made to bond to plastic will help a lot as well.
There is a lot to this topic.
Make sure the surface is completely clean of all oil, armor all etc other wise the paint will fish eye.
You should primer the surface to allow,the color coat to bond to the surface. Also depending on the color you may need a light or dark primer.
Are you using color match paint? Is it single or dual stage or are you using krylon?
If its just krylon, then paint away.
If its a color match, that's different. Read the accompanying documentation that comes with it from the paint store! It will tell you time between coats, whither you need to sand between coats and when to apply the clear if needed.
If its a single stage paint (meaning the clear and hardener are mixed as one) then you will just apply the right number of thin coats until it reaches the you are attempting. Then let dry and harden and your done. No need to clear it as it is already part of the paint.
If it is a 2 stage paint ( the paint and clear coat are applied separately) then you will apply x number of coats to reach the color you are attempting, then apply 1or 2 coats of clear and let it dry and harden. If you do not apply the clear then the paint will be dull. Clear is where the gloss comes from.
