leave em on and paint the whole damn car. if you take them off to get painted 1) youll probably break something 2) when you put them back on they will look nice and new and make the rest of the car look like *BLEEP* 3) if u try to paint just them and leave them on the car it will look stupid and youll see the line 4) and dont try to fade in into the rest of the car because by that time youll be using so much paint it would be better to repaint the whole car like i did.
hope that helps you from making a stupid mistake, besides you drive a lexus. do things the right way... not the ricer way.
