Car Nissan Qashqai the second generation (J11) has a modern design, where body aesthetics play an important role. One of the important elements of the exterior is windshield molding, which not only performs a decorative function, but also serves as reliable protection for the junction of the glass and the body. Over time, this element is exposed to aggressive environmental influences, which inevitably leads to its degradation.
Many owners are faced with the need to replace this part after an accident or simply due to loss of appearance. Replacing molding - This is a procedure that requires accuracy and understanding of the body structure. Improper installation can lead to moisture penetration into the interior and corrosion of the metal elements of the glass frame. In this article we will look in detail at how to choose a quality element and install it correctly on your car.
The role and purpose of molding in body structure
Molding installed around the perimeter of the windshield on Nissan Qashqai J11, is a long plastic or rubber pad. Its main task is to hide the adhesive seam that attaches the glass to the body and prevent water from getting under the edge of the glass. Without this part, the tightness of the structure is compromised, which creates serious risks for the vehicle's electrical equipment.
In addition to protecting against moisture, the element serves as an excellent damper, dampening vibrations that occur when driving over uneven roads. It also prevents chips and cracks on the edges of the glass that can occur due to small stones or branches. Plastic molding on this model it often has a chrome or black glossy surface, which significantly affects the perception of the carβs appearance.
It is important to understand that if the molding is damaged, both aesthetics and functionality suffer. If you notice gaps or peeling, you need to take immediate action. Ignoring the problem may cause water to begin to accumulate in the area of ββthe dashboard and fuse box. Joint tightness - this is the key to long service life of the windshield and the absence of electrical problems.
β οΈ Warning: A peeling molding can come off at high speed and cause an accident or damage to the vehicle behind you. Don't leave the problem unattended!
Causes of degradation and signs of the need for replacement
Operating a car in harsh climatic conditions leads to rapid aging of polymer materials. Ultraviolet radiation is the main enemy of plastic, making it brittle and brittle. In combination with temperature changes and reagents on the roads, the molding loses its elastic properties and begins to crumble.
Common signs that a part needs to be replaced include cracking, discoloration (fading or yellowing), and loss of seal. Often owners Nissan Qashqai they notice that the molding simply peels off from the body, creating a gap. In this case, water will inevitably enter the cabin, causing an unpleasant smell of dampness and mold.
- π The appearance of visible cracks and chips on the surface of the molding
- π Delamination from the body and formation of gaps around the perimeter of the glass
- π Water leaking into the interior when washing or heavy rain
- π Unpleasant smell of dampness or mold in the front part of the cabin
Sometimes the problem may be hidden. If you notice that traces of water have appeared on the windshield, but the molding looks intact, the structure of the material may be damaged at the micro level. In such cases visual inspection may be insufficient, and it is better to replace the part preventively.
Types of moldings: original or analogue?
When choosing a replacement from the owners Nissan Qashqai J11 There is always a dilemma: buy an original element or opt for a high-quality analogue.

Preparation for installation and necessary tools
Before starting work, it is necessary to prepare the workplace and collect all the necessary tools. The replacement process requires care, as you will be working with fragile glass and body paint. You will need: a set of screwdrivers, a plastic spatula, degreaser, double-sided tape (if not provided on the new part) and a new molding.
First, the car must be thoroughly washed and dried. Pay special attention to the area where the molding will be installed. Any dirt or remnants of old glue can interfere with quality fixation. Use degreaser for surface treatment before gluing a new part.
If the new molding already has an adhesive base, this greatly simplifies the task. Otherwise, you will have to apply the double-sided automotive tape yourself. It is important that the tape is of high quality and can withstand temperature changes and vibration.

Step-by-step instructions for replacing molding
The process of removing old molding begins with dismantling, if necessary, decorative plugs in the corners. Carefully pry the molding with a plastic spatula and slowly pull it towards you. Do not use metal tools to avoid damaging the body paint or the glass itself. If the part is stuck, you can warm it up a little with a hairdryer to soften the glue.
After removing the old element, it is necessary to thoroughly clean the surface of any remaining sealant and tape. Use a special solvent to remove adhesive residue. The surface must be perfectly smooth and clean. Remains of old glue can cause an uneven fit of the new part.
Before installing a new molding, place it on the glass without removing the protective film from the adhesive tape to make sure the geometry is correct. If everything matches, remove the protective layer and gently press the part, starting from the center and moving towards the edges. This will help prevent air bubbles and gaps from forming.
Make sure the molding fits snugly all the way around. You can press it lightly with your hands or use a soft sponge for better contact. Do not try to pull the part too tightly so as not to deform the plastic. Uniform pressure - a guarantee of tightness.
β οΈ Warning: Do not drive or pressure wash your vehicle within 24 hours of installation. The glue needs time to fully polymerize.
What to do if the molding doesn't hold up?
If the molding does not hold well, the surface may not have been degreased or low-quality adhesive tape was used. In this case, you will have to remove the part, degrease the surface again and apply a new layer of high-quality automotive tape.
Common installation errors and their consequences
One of the most common mistakes is haste. The owner tries to immediately start using the car without allowing the glue to dry. This causes the molding to peel off due to wind and vibration. Drying technology must be strictly observed.
Another mistake is using inappropriate adhesives. Ordinary household tape will not withstand the thermal expansion of plastic and may fall off during the first winter. Use only specialized automotive materials designed for working with plastic and metal.
- π οΈ Ignoring cleaning the surface from old glue residues
- π οΈ Using metal tools to remove molding
- π οΈ Attempted installation at subzero temperatures without heating
- π οΈ Insufficient pressure on the part after sticking
If you are not confident in your abilities or are afraid of damaging fragile glass, it is better to entrust the work to professionals. An installation error can lead to repairs that are more expensive than the cost of the part itself. Professional installation guarantees long lasting results.
Before starting work, measure the ambient temperature. Ideal conditions for stickers are from +15 to +25 degrees Celsius.
