How to Restore Headlights PERMANENTLY
Automobile’s optics is truly affected to the mechanical influences during exploitation of a car. It could happen because of accident or because of owner’s carelessness. Today it’s possible to buy new details in a shop and replace all damaged details. But the majority of car owner prefer to repair their cars by themselves.
Why? Well, new details often cost enough much. Furthermore, it’s hard to find spares for some automobiles. These two facts are probably enough reasons for repairing cars independently. At least, it’s not so hard to repair headlights by own hands!
It’s possible to restore the integrity of optics by different ways. The choice of way depends on degree of optics’ damage. It’s possible that some special instruments and welding device with compressor will be required for the work. Welding device is useful for welding on headlight’s fragments, if its integrity would be broken.
About self-restoration of headlights in detail
The restoration must be started by determine a material of optics. If headlight is from plastic, cold welding is appropriate for restoration. If optics is made from polypropylene, welding will be the right choice. It’s important to keep in mind that connection between different kinds of materials will probably be insecure.
Headlights’ restoration is necessary not only because of mechanical damage, but also because of little clouding. Clouding strongly affect on the headlights’ ability of omitting light, which could become a reason of accident in the dark time of day.
There are widespread defects of optics:
- crazing of headlight’s body;
- damage of elements of headlight’s fixation;
- depressurization of seams;
- different scratches and cleavages, which arise during a car’s exploitation.
Headlight’s becoming misted could seem as insignificant problem prima facie. Car owners usually don’t pay attention at this trouble. But if this defect will not be corrected during 1-2 months, the mirror layer of deflector can start to collapse. Also, it’s possible that acidification of contacts will start in this place because of accumulation of moisture. Because of such accumulation other troubles also can arise.
Scratches on the optics are the event that is widespread. Car owners also don’t always pay attention enough at this event. It’s necessary to grind a headlight and polish it carefully. Such repairing can let car owner get rid of even deep scratches and improve the appearance of vehicle’s optics.
Something about fur
It’s possible to find a fur on inside part of headlight. A possible reason of its onset is infiltration inside by chemical reagents (usually, during contactless car’s washing). Under the influence of high temperature such fur can form cloudy film and decrease the headlight’s ability of omitting light.
It’s better to fix such defect in the special car services, because it could be enough hard to make it by own hands. Cracking of headlights’ protective layer, which is exist on many modern automobiles, is also a serious trouble. It can decay because of long time of using, because of natural reasons, because of ultraviolet’s influence or because negative influence of chemical substances.
In some cases it’s impossible to fix completely such defect, because it could be impossible to reach damaged place by arm or special equipment. If man isn’t sure in his professionalism and he has not necessary practical skills, he shouldn’t make restoration of plastic headlights. Otherwise, the risk of additional destruction of optics’ plastic on its mirror layer is big.
Before the beginning of all works it’s necessary to clean headlight carefully and make attentive check of defect. Because of such check it’s possible to find cracks in it, which is necessary to fix completely. Well, if there are not defects that mentioned above, it’s acceptable to start restore headlights by own hands.
More specifically about restoration
Repair of cleavages and scratches must be executed fully according to technology and in the next sequence:
- The place of cleavage must be carefully washed out and completely dried.
- It’s necessary to install injector in a center of damaged place. Polymeric mix for pasting goes because of it.
- The volume of cleavage is filled by glue’s composition. It’s necessary to control that the air vials will not arise.
- After that injector must be taken away and glue must be dried by the ultraviolet lamp. The repair of headlights reflector can be executed by the same method.
- Then, for increased durability of repaired place, it’s acceptable to additionally work up it by a hardener.
- After the full congelation of mix, the all irregularities of surface must be fixed by file. After that, headlight must be polished by polishing machine or emery paper of little abrasiveness. Then the final polishing must be done for giving a glitter for optics.
About some other important details
The repair can be done by different ways, but most simple method for fixing defects of plastic headlight is its welding by pumping of hot air. It’s possible to return unpinned parts of optics to their place by this way (the method of sticking is not very effective in that case).
It’s necessary to remember one important detail during repairing: only welding of the same kind of plastic is acceptable. Otherwise, repaired headlight will serve no more, than two weeks.
Well, the repair of headlight’s fixation truly harder. It’s better to let professionals do this. The welding of this area will be ineffective and headlight will be destructed soon. Therefore, specialists with big experience recommend to restore headlight’s body by prosthetics. Some metal parts are changed by other ones, and headlight gets its location.
Polishing and grinding will help to repair headlight, if it lost transparency. It’s necessary to use thin polishing that will not damage optics’ protective layer. After finishing of repair it would be good to glue over by antigravelly film for additional defense of headlight.
