Step-by-step instructions on how and with what to glue the windshield to the car door yourself


Not all cars have windshields on the side windows. Their factory installation is not provided by the manufacturer for all car brands, so many owners attach the cutoffs to the body or window themselves. “Visors” perform a decorative and protective function.

You can install window deflectors on your car at a service center, but this is not a cheap service. It is possible to do the installation of the device yourself. To glue protective windshields, you will need special tape, clips or fasteners.

How to glue side window deflectors to a car

Almost all models of windshields are produced already equipped with an adhesive strip. This turns the process of gluing elements into a 10-minute task. The main condition is to be careful and attach the parts exactly the first time. Otherwise they will lie crooked, so you will have to tear them off and re-glue them.

If the fairings you purchased are not equipped with an adhesive layer, purchase special adhesive tape from the auto store. Before work, it is heated with a hair dryer. The main advantage of this adhesive material is ease of use. You don’t have to drill anything or use additional fasteners; your car doors will remain without a single scratch.

Preparing the surface and car for installation

In order to beautifully glue deflectors on car doors, you need dry, warm weather of at least +15°C. Place everything you need for work next to the machine:

  • construction hair dryer;
  • set of wind deflectors;
  • adhesive tape, preferably SA-Plastik, AutoAx, SIM;
  • dry rags;
  • technical solvent.

Prepare the surface of the side windows:

  1. Wash your car, carefully going over the areas you will be working on.
  2. Wipe the fastening points of the windshields with solvent.
  3. If the body panel has previously been polished using wax or paraffin mastics, clean the areas where the fairings are glued more thoroughly.

How to safely remove old adhesive from baffles

When replacing cutters, first remove the old glue from the previous parts. There are a couple of effective ways to do this:

  1. Take a drill, attach a butterscotch bit to it and go around the door frame, carefully removing the old adhesive layer. Experienced professionals recommend using a nipple from a tubeless tire as an attachment. Treat the areas with anti-glue - anything left after the drill will be easily removed.
  2. If you don’t have a drill, apply Horse lubricant to the layer of old glue. Wait 15-20 minutes, then remove everything with a dry cloth.

Be careful not to rub too hard to avoid damaging the surface of the window.

Instructions for installing window deflectors without gluing

There are many ways to attach windshields, sometimes there are ones that do not have an adhesive strip or fasteners. On a number of VAZ car models, cutters can be installed without any fasteners. What it looks like: the plates are of such a size that when fixed, their edges rest against the corners of the window frames. At this time, the side is held in place by a glass seal or so-called velvet.

  1. Lower the glass a little before installation.
  2. Arm yourself with a thin plate of durable material.
  3. Pry up the seal on the outside of the window where the fairing will be attached and peel it off.

The rubber band does not stick on its own, but there is a possibility that it will stick to the anti-corrosion lubricant. It is used to treat the window frame after painting. Slightly bend the windshield in the middle part, insert the outer side into the gap between the door frame and the seal. Raise and lower the glass - if the cutter is installed correctly, it will fit freely into the seal groove.

Correct selection of device

First of all, when choosing window deflectors, you need to remember that they are purchased exclusively in accordance with the specific brand and type of vehicle. There are no universal models, because the design of the body and windows of each car model is unique. The main criterion by which all devices are classified is the method of attachment to the car window. On this basis, the following categories are distinguished:

  • Side window deflectors with a screw connection, for installation of which it is necessary to damage the hood and door frames by drilling holes in them;
  • Devices that are mounted on a double-sided elastic lining treated with an adhesive liquid;
  • Combined deflectors. Their design combines several methods of mounting on car windows;
  • Side window deflectors, which are attached using special clamps and brackets.


Window deflectors
Units for the installation of which require drilling holes, thereby compromising the integrity of the car body coating, are becoming less and less popular. The most common installation methods today are the following:

  • Glue the device with adhesive tape or insert it under a rubber gasket (used when working with window deflectors);
  • Secure the device using clamps, brackets and special adhesive pads.

Problems when installing deflectors on side windows and their operation

Novice drivers do not always know who, how and with what glues windshields to the car door. In view of this, manufacturing companies equip their products with good adhesives. For example, high-quality 3M glue is used on the elements. However, the plates may not stick at all, only stick halfway, or come off while the machine is moving.

Double-sided tape will be your salvation in such a situation:

  1. Take some duct tape and cut a strip of it the same size as the windshield plate.
  2. Apply one side of the tape to the fairing.
  3. Place the other side of the adhesive strip on the door frame.
  4. Follow the same steps if you want to re-glue the fairing. First wash the place where it is attached with warm, soapy water, then go through it with a solvent to completely remove excess previous glue.

For some reason, everywhere they sell the option of two windshields per side. I saw on one viburnum, it has a small third windshield above the small rear side window

Above, seppo wrote that these are sold in Ladya.

what's the point in it? porn in my opinion

Yes. It’s convenient to smoke in these things, but I’ll never use them for myself.
