Gather your tools. A Flat head screwdriver, a star screwdriver, a 10 inch socket and ratchet. A high gloss high temp black paint, primer, and i used black silicon (i used black gasket silicon), masking tape.
First off you will need to take off the bumper. 8 clips at the top, 6 screws at the bottom, and a few clips underneath as well. Follow this.
Nissan Altima Coupe Bumper Removal
Start Removing the bolts with the 10mm socket and ratchet and use the star screwdriver for the three screws.
You then remove the headlight and wire off the holding clip and all the bulbs and remove the 2 star screws at the back of the headlight housing.
After you’re done with that you’re going to set the oven preheat at 350*. Make sure you have a sort of pan and foil wrap underneath on the parts on which it leans on so those don’t melt. when the oven is finished preheating put it in for about 6 minutes.
Make sure you have your space provided to pry open the headlight which you must immediately after taking out make sure your wearing some sort of gloves to protect from the heat, its hot.
Keep prying it open until it’s fully opened. Now you’ll remove the 2 star screws on the inside and separate the pieces to remove the big orange reflector.
Begin sanding down the chrome pieces. I used a 320 fine sand paper and mask the areas in which you don’t want painted and have your primer ready in the painting area although some people painted the chrome section off the yellow turn signal area i left it chrome to distinguish it from the rest.
Now you begin to primer and paint, I used 2 coats of primer and 2 coats of paint about 15 minutes in between coats of primer and 25 minutes for the paint between the coats.
Now removing the masking tape and put the pieces back together put the black piece connected with the headlight face then the small chrome piece screwed on behind it clean out the dried clean from the back of the housing so you can re insert the front with the back piece
Your going to want to bake the back piece of the housing in the oven again for 6 minutes .. again once done with this make sure you have your silicon in hand and ready to put it together begin putting it together now it should put it silicone the edges of housing insert the 2 pieces together and mold back the black edges together and apply a thin strip of silicone between.
Let it dry for a few hours, reconnect the headlight, lights etc, and reinstall the bumper.
