if its plastic you will need to solvent wipe it to remove oils and greases. then prime with plastic primer. then a few caots of normal primer, flatting inbetween coats with p800 wet or dry. then the base coat of your choice followed by 2 or 3 coats of clear laquer.

if its alloy then replace plastic primer with etch primer

For the plastic pluig lead cover there's no need for plastic primer as its a non-flexing part, it just sits there (unlike bumpers etc) just make sure its totally grease free, use some 'cheap' thinners carefully to wipe it over, and do it at least twice let it dry thoroughly, then prime, let it dry over night to adhere and sink (its on plastic ;)) then paint with very light coats of paint in a warm environment.

If the primer looks 'rough' sand it lightly with some 400grit paper and blow all the dust off before painting.

etch primer (high acid content) is best used on smooth bare metal surfaces exposed to the elements as the acid 'eats' into the smooth surface providing a key (lightly sanding with 400 to take the shine away from the clean metal has a similar effect, Red 'oxide' or even high sulphur content primer is good on clean metal elsewhere.
