|Thorough cleaning beforehand.|
As much as I regret it, with a job like this at hand, the inexperienced worker can't be spared the manual labour. For those who can't- or don't want to the work, go to a professional. Indeed, it would be wise to get a few
quotes for new headlamps and their installation or adjustment beforehand. However, any really big savings can only be achieved by doing it yourself.
|Masking tape on the not affected body parts.|
Before you start, it must be determined whether the cover is actually plastic (acrylic glass) and whether any foil or pieces of foil still exist. They must be removed, either by using a high-pressure steam cleaner (don't
get too close!), special adhesive tape or through artificial cooling and rubbing. This is to be followed by checking for possible scratches, which can be removed with the help of a very fine sandpaper (Video 1).
|Start with the finest possible sandpaper.|
What then follows, is the polishing, it should however be a special polish for the plastic headlamp covers or a glass-cleaner. If this was my first attempt, I wouldn't use a buffing-machine on the expensive headlamps
from the start. The whole thing could become too hot too quickly or it could cause streaking. Apart from that, the buffing machine should only be used on dismantled headlamps.
|Wet sanding is important.|
Finally, the sealing is applied, which hopefully, not only protects against ultraviolet rays. In this case, a two-component, clear varnish is recommended. After shaking it well, it is then evenly and thinly applied. By the
way, the headlamps are there to ensure safe driving when it's dark and shouldn't only be checked just before an appointment for an MOT. 05/15
