I looked around and found some write ups on how to smoke your lights using VHT Nite-Shades. But none of the write ups i found involved our gm trucks! This process can work for headlights and fog lights, too! ..So, here we go.. These are the things I used. Obviously you can use different things, but it worked great for me. VHT Nite-Shades (bought mine from Autozone) Duplicolor Clear Coat (again, bought it at Autozone) Some type of scratch remover Gloss polish (as you can see, I didnt have gloss polish, so I used chrome polish) A "wipe and shine" cleaner Painters tape Spray bottle with a water and soap solution. Microfiber cloth 800, 1000, and 2000 grit "wet or dry" sandpaper Buffer Directions 1. Remove the taillights from the vehicle 2. Tape over the holes on the back to prevent dust/paint from entering 3. Sand the lights with 800grit sand paper to remove the clear coat 4. In a well-ventilated area, spray on the Nite-Shades in even, light coats. Light coats are important to prevent runs. Also, its easier for you to decide how dark you want to go. I only did two coats, but should have gone one more. 5. After you have gotten your lights how dark you want them and they have dried, its time to DRY sand them. With 1000grit sandpaper, sand the lights to remove any pits, scratches, etc. Wipe the lights off with the microfiber towel. 6. Spray on the clear coat next. I did two heavy coats, but be careful not to let it run! 7. After your clear coat has dried, spray the lights with the soapy water and wet sand with 1000grit sandpaper, then wet sand with the 2000grit sandpaper. Make sure its as smooth as it can get before buffing. 8. Next, I tapped off the area around the lights to prevent anything from getting on the paint. 9. Reattach the lights and buff with the scratch remover and buffer. I didnt need to push hard with the buffer. Just let it do its thing. Wipe of the excess with your towel. 10. Next, buff with the gloss polish. Again, wipe off the excess. 11. Wipe clean with the "wipe and wash" spray and BAM! Congrats, you have a set of tinted lights! If they didnt shine enough for you, repeat steps 9 - 11. Any questions, feel free to ask!! Good Luck!
