Changing colour of vent covers
 

My Spyder has the lovely combination of red / black trim , except for the front and side vents that are silver.
I checked to see if black ones are available but they are not , hence why it was supplied with silver ( titanium).
The price of these are well over a hundred each so not cheap to buy a set and get painted. Also my trusted painter advised not to as the paint wont last well. So i never had anything wrapped before but that looks the only choice now ? Anyone else been down this path ?

I painted my front bumper grills and side vent grills about a year ago and they have held up well so far... I used a paint that was made for use on plastic. Apparently it bonds to/with the plastic.
For the side vents I just removed and painted the grill inserts, not the outer trim. I painted the front grills while I had the bumper off to clean the radiators. Its simple enough to remove and repaint them if they start to look rough in the future.

Black plastidip works great on the front and side vent louvres. It has a nice satin finish and unlike paint, it won't chip.

I too painted mine with vinyl paint... it was just about a month and a half ago so no idea how long it will last. Since it is a good idea to remove the bumper to clean the radiators regularly it doesn't take a lot more time to touch up the grills each time while you are at it.
