Our Windscreen Repair Blog
Why do we use a UV protector ?
Before we release the windscreen repair resin onto the windscreen we cover the repair bridge and injector with a UV protector. The reason why we do this is because ultra violet light cures the resin. So because of natural UV light we cover up because we don`t want the resin to cure before its filled the chip repair.

MOT laws regarding windscreens
There are two zones on the windscreen that apply to the MOT laws in the UK. We have the A zone and the B zone, Zone A is the center of the steering wheel and it measures 290mm across in the swept area of the wipers. Zone B is the rest of the swept area of the windscreen wipers.
In the zone A the MOT law says that any windscreen repairs in that area cannot be any bigger than 10 mm diameter.
In the zone B the MOT law says that any windscreen repairs in that area cannot be any bigger than 40 mm diameter.
There are a few different types of windscreen repairs above, we have some examples.
De-laminating windscreen repair
Look at the windscreen repair above, it`s got a milky white shadow in it. What’s happened here is contamination from moisture has entered the windscreen repair and attacked the PVB plastic interlayer which is in the middle of the two layers of glass. The moisture turns the laminate this white color and its permanent. The best way to avoid this happening to your windscreen repair is to get the stone chip fixed as soon as possible.
Well, look at the picture above, this was a perfectly good Bull`s eye windscreen repair and could have been repaired to near perfection. But my customer kept saying “it will be ok, I will get it sorted next week” well it didn’t and he had a new windscreen replacement costing him lots more money than a windscreen repair would have cost him.
I think I’ve got a windscreen repair?
Well, actually this windscreen repair has already been repaired. We come across this type of thing lots and as you can see looking at the picture only half of the legs on the windscreen repair have been filled with resin. It`s a bad job any one of them legs could crack off. Look where the arrow is pointing, that is the pit area the point where the stone hit the windscreen causing the windscreen repair. On the surface of the pit area, you can see resin so that tells me the repair has already been done.
A windscreen repair will never disappear completely. Take a look at the pictures above the windscreen repair is a classic Star break repair. Sometimes these can be a bit tricky, mainly because the legs could be separate from the rest of the repair, not connected. When the legs are connected we usually get good results from the repair, but if you look at the second done picture you can see three very faint lines that are called scarring. But the windscreen repair is filled full with resin.
My windscreen cracked for no reason.
If your windscreen cracks for no reason and you can`t see any stone chips this is usually the reason why. Take a closer look where the arrow is pointing, its a very small stone chip and it is hardly visible but this little stone chip cracks the windscreen instantly. This type of damage usually happens around the edge of the windscreen.
