The exterior of a car often becomes the calling card of its owner, but it is the interior details and the condition of the luggage compartment that speak of attentiveness to the car. On Nissan Sunny The trunk lid trim is an element that is subject to serious stress: temperature changes, moisture and constant vibrations take their toll over time. The plastic cracks, and decorative fabric or velor begins to peel off, creating unpleasant visual noise.
Many owners are faced with the need replacing the casing not only for aesthetic reasons, but also to restore heat and sound insulation. Ignoring this problem can cause water to begin to accumulate in the cavities of the lid, causing corrosion of the metal. In this article we will look in detail at how to properly dismantle the old coating, prepare the surface and install new material so that the result will please you for many years.
Symptoms of wear and causes of material deformation
The first sign that your Nissan Sunny repair is required, is the appearance of bubbles on the surface of the casing. This occurs due to the loss of adhesion of the adhesive layer, which dries out over time when exposed to sunlight. In winter, water that gets under the material freezes and expands the peeled areas, making the defect noticeable immediately when opening the trunk.
The second common problem is mechanical damage to the plastic or metal base itself. If you frequently load the trunk with heavy items, impacts may cause cracks in the trunk. rigid basis. In such cases, simple re-gluing will not help - it is necessary to restore the geometry of the cover. Pay attention to the condition of the plastic clips that hold the trim in the groove: they often break, leaving the fabric dangling.
The condition of the casing in the area of ββthe lock and the window lift mechanism (if this modification has one) is especially critical. This is where the maximum concentration of forces occurs when opening and closing. It is in the lock area that a gap most often forms, through which moisture and dirt get inside. If you notice that the fabric is sagging or loose in this area, you should not delay repairs, as this may lead to electrical equipment failure.
Selection of materials for restoration and replacement
When choosing a siding material, you have several options, each with its own pros and cons. The most budget option is to use automotive felt or foam rubber and then cover it. However for Nissan Sunny it is better to choose more durable solutions, such as carpet or Alcantara. These materials are abrasion resistant and do not absorb odors.
If you want to maintain the factory look but improve the quality, you can purchase a ready-made trim kit designed specifically for your model. In specialized stores, you often find sets that include not only fabric, but also new plastic clips. It is important to consider the thickness of the material: a layer that is too thick may not fit into the fastening grooves or interfere with the operation of the trunk mechanism.
Don't forget about the adhesive composition. Regular Moment glue will not work here, as it loses its elasticity in the cold. Use a special automotive spray adhesive, such as 3M Super 77 or similar compounds designed for use on textiles and plastics. They provide reliable adhesion and retain their properties over a wide temperature range.

- β¨ Alcantara - premium appearance, tactilely pleasant, more expensive.
- π‘οΈ Velor - a classic option, it dampens noise well, but gets dirty quickly.
Removing old cladding and preparing the surface
The process of removing the old casing requires care so as not to damage the plastic insert or the metal base of the cover. Start by unscrewing all visible fasteners: handles, decorative caps and lock latches. Use a plastic spatula to pry up the edges of the trim without scratching the metal. Work slowly, gradually releasing the glued areas.
After removing the fabric, it is necessary to thoroughly clean the surface of any remaining old glue. This is the most labor-intensive stage, since the reliability of the new fixation depends on the quality of cleaning. Use solvent or a special degreaser, but be careful with the plastic so you don't melt it. The surface must be perfectly smooth and dry before applying a new layer.
In some cases, the old sheathing may be glued to the foam layer, which has already turned into crumbs. In this case, you will have to remove this layer too, leaving only the hard base. If there are traces of corrosion on the metal, they must be cleaned with sandpaper and treated with an anti-corrosion compound. Ignoring rust will cause it to continue to spread underneath the new material.

Instructions for installing new casing
Installation of new material begins with fitting. Lay a piece of fabric over the lid to make sure it is the right size. Leave a margin of about 2-3 centimeters at the edges for bending into the grooves. If you are using a foam backing, glue it to the fabric first and then to the lid to avoid air bubbles. Applying glue It is better to produce in two layers: the first for the primer, the second for the main one.
After the first layer of glue has dried, carefully apply the fabric to the lid, starting from the center and smoothing it out to the edges. Use a roller or clean, dry rag to remove the air. Pay special attention to the corners and areas around the mounting holes. Carefully trim the excess fabric along the edges with a sharp stationery knife, leaving a small fold for fixing into the groove.
Return all plastic elements to their place: handles, plugs and lock latches. If the old fasteners are broken, replace them with new ones to prevent the trim from sagging. Make sure that the trunk release mechanism works freely and that the fabric does not interfere with its movement. Make a final inspection, checking that the material is stretched and wrinkle-free.
βοΈ Preparation for installation
Before applying glue to the entire surface, test it on a small piece of fabric and plastic to ensure there is no chemical reaction or staining.
Elimination of sagging and squeaks
Even after a high-quality installation, over time the casing may begin to sag or creak due to vibration. This often happens due to improper tension or the use of poor quality glue. To correct the situation, it is not necessary to remove the entire coating again. In some cases, it is enough to pinpoint the problem areas using a syringe to apply glue under the fabric.
Creaking can occur due to fabric rubbing against plastic clips or metal edges. To eliminate this problem, use special silicone-based lubricants or place a thin layer of felt between the fabric and the plastic at the contact points. Also check the condition of the plastic clips: if they are loose, replace them with new ones or place a sealing washer under them.
If sagging is observed in the center of the lid, it may be a sign that the material has stretched. In this case, installing additional attachment points or using a stiffer material will help. Regular inspection the condition of the trim will help prevent serious problems in the future and maintain a presentable appearance of the luggage compartment.
