hi all touareg lovers.
i got my 05 V8 for 4 years now and my headlights have been going more and more hazy and yellow but i did not want to do it in the way as most of the guys do, polishing and buffing it out it just waste of time as they will become yellow again very soon.
probably most of you know that there is factory protecting film coating on the headlights but eventually it fails, especially if the car is parked outside in the sun. the biggest problem is the suns UV rays and oxygen,
here is the step by step guide how i restored my headlights, and i think its the best and most long term protection.
step 1 : remove headlights
step 2 : prepare sandpapers 400, 600, 1000. 1500. 2000. and 2500 grit
step 3 : you will need a hose or a bucket of water
step 4 : start sanding with 400 grit sandpaper, always keep the surface wet. this is the most important step as you will need to remove all the old yellow film and stone chips and every scratch that needs to be removed. remember that 400 grit removes everything tat needs to be removed and other grit sandpapers are only used to make surface more and more smooth so it will be possible to spray the clear coat on them.
step 5 : as you increase the grit, you have to remember that if you have not removed all the unwanted stuff from your headlights with 400 grit 600 grit will not do the job. only reason you will use 600, 1000, 1500, 2000 and 2500 is that you will need to make it as smooth as possible. as i said earlier you need to keep surface wet all the time, dont forget to do all the surfaces evenly with all grits you use.
step 6 : when done with sanding rinse it with water and wash off all the remaining dust from the surface of the headlights and let it dry throughout for at list 4-5 hours.
step 7 : before spaying clear coat use rubbing alcohol to remove any unwanted contamination from the headlight surface.
step 8 : choose the clear coat that will protect from UV rays and it will be as transparent as possible, you can also add some color to it if you want to. like little bit of black or blue or violet to have more effective looks,
i asked my friend to spray the clear cot for my as he is a professional and he knows how to do it in the best way, we used ceramic clear coat and little bit of violet paint to make it look fresh. color is hardly noticeable.
after spraying 2-3 layers of clear coat you may have a little bit of ''orange peel'' and you have to use 3000 grit Trizak and than buff it out with a polishing machine
in my case i did not need it as my friend dose have some magic hands
he is one of the best car painters here in Tbilisi. Georgia.
if you will have any questions ill be happy to help
