The glass, together with all the so-called transparent “plastics”, is one of the main elements that are part of any vehicle. In the eyes of all the windshield jumps, which over the years has been subject to many evolutions and updates that have increased its resistance and consequently the safety first of all for the driver but also for all the other occupants of the vehicle. Advances in this fundamental component of each vehicle also affect its own maintenance, often necessary since damage to the windshield is unfortunately not extraordinary.

To reflect on the progress made over the years, it is sufficient to compare the former windscreen with the current ones: in the beginning they were made with the same glass as our windows, and therefore in case of breakage the splinters were sharp and razor-sharp, while those of today, although still in glass, are made with two layers of glass foil divided by a plastic film, which in perfect adherence becomes invisible and essential for our safety since in the event of a collision with something it acts as a glue and the glass splinters remain glued even if fractured with the typical design in the shape of a spider web. I’m there are several causes which lead to damage to the windshield, in addition to the inevitable acts of vandalism: let’s think about accidents, or extreme temperatures, or even collisions with suspended objects.
Three very different circumstances, as the precious advice offered by also reminds us ReteRiparo, an emerging reality in the world of car workshops. When it comes to accident cases, our windshield is designed for resist breakthrough, of course within certain limits and cases, so it will be damaged without shooting sharp shrapnel at the occupants of the vehicle. As for the sudden changes in temperature, however, micro fractures can be created due to the rapid expansion or shrinkage that the rubber seals are unable to limit or accompany: this generally happens more to the rear window. The last circumstance concerns the suspended objects, to give an example, the loose pebbles that hit our windshield: in this case it must be said that the extent of the damage varies according to the speed of impact, and it should be specified that if this is slight, specialized companies can be used which in a short time and with a decidedly negligible cost when compared with the cost of a new glass are able to repair the damage with excellent results.

Another element in which glass is a fundamental part are i headlights. Also in this case, the design techniques have evolved a lot over the years: while once the lighting was directly integrated into the frame, today we have a single block that fits into special housing sections, and it is no coincidence that we have to deal with non-repairable faults the headlight is changed in full and not simply in part. Recall that each lighthouse is made up of one protective outer shell, which is not in glass but in a polymer that we generally call plastic and which has the purpose of protecting the lens and the lamp in case of atmospheric events or shocks. Over time, however, this polymer tends to yellow, greatly reducing the illuminating capacity of our car: in this case it is not necessary to think about a replacement, since a little elbow grease, a kitchen sponge and some specific products to restore the lighthouse to its original transparency.
Final remarks on the mirrors, inside and outside the passenger compartment. As it goes without saying, the latter are more subject to shocks and damage. If one of these scenarios arises, there are two solutions: resort to the spare part at the car manufacturer of our vehicle, which will sell a whole new mirror complete with electric motorization (and therefore there is also the obligatory passage to the workshop to be carried out on site), or if the cap has not suffered damage go to a junkyard to see to recover only the mirrored part.
