You should apply Nanolex Si3D Headlight in a warm, dry, well-ventilated space out of direct sunlight. For your comfort and protection, we recommend wearing PB Nitrile Gloves and a 3M Respirator during the application process. In all cases, prepare the surfaces you are going to treat in the normal way (wash > decontaminate > polish), and then do a thorough wipe down with Nanolex EX to ensure that they are spotlessly clean. Next, using a Nanolex Si3D Applicator Towel wrapped around a Nanolex Si3D Applicator Block, spread a thick layer of Nanolex Si3D Headlight on to the first light cluster, using light pressure and overlapping strokes. Then, continue spreading the product in a criss-cross fashion until it completely disappears. Next, finish the levelling process by buffing the treated light cluster with a Nanolex Microfiber Buffing Towel. Finally, using a bright light, check the light cluster carefully for any smears and remove them before moving on; failure to remove smears fully can result in them hardening to the point of being impossible to remove without machine polishing, so make sure you are thorough!
After all of the light clusters are treated the car must then be left in a warm, dry place out of direct sunlight for a minimum of 12 hours to allow the coating to harden (if you wish, you can accelerate this process by heating the treated light clusters to 60°C for 10 minutes using an infra-red heat lamp). Note that in order for the coating to harden properly it must remain completely dry during this period, and you should also avoid washing the car with any kind of detergent for the first 3 days afterwards. Please note that you must discard all used applicator towels and buffing towels after each application, because Nanolex Si3D Headlight hardens massively as it cures, forming a residue that has the potential to inflict severe marring or worse if applicators and towels are re-used. Please also note that the quoted shelf life of Nanolex Si3D Headlight is between 3-6 weeks once the bottle is opened, although this can be extended to 2-3 months if it is stored in a refrigerator.
