If you have a simple color, like black, it should be easy, however, if you have a metallic color, it would be harder.
Get factory touch-up paint for your color, thin it out with a little reducer, and spray it on using an airbrush. Don't forget the clearcoat.
Or, just take the eyelids to a body shop, have them spray them in the same color of your factory coat, shouldn't cost you much of anything to do this, $30-$40 tops, that's with clearcoat. When they're painted, install them yourself with 3M tape. If they charge you $100 to spray two little pieces of plastic, they are screwing you.
I think that paying $200 for pre-painted eyelids is insane! that's just my opinion.
Honestly, I don't know why you guys pay so much money for your mods, Whatever happened to budget build-ups?
