I removed all OEM decals, had a decal guy make templates for the painter to use, sprayed base black / matte finish clear, it looks more black without the shine of gloss. I do nothing special to maintain them, I Zaino the entire painted surface just like they are not there and they have not glossed. I did this back around March of 2006 and still look great.
my mango has been de-striped too. having DAYTONA plastered down the sides attracted far too much attention from the ******* types here in SC. i have gotten alot more compliments (from people with all their teeth) since i took them off.
