i had a simlar problem with my trim on my eg, but it would be faded black, and not so good looking. i popped off the pieces that would come off (to reveal a but load of leaves and crap) and just simply hosed em down, and then painted them with basic black primer, nothing fancy and it did the job great, and if i felt bored, i would use clear coat on em, dont know if i used enough to make a difference though.
