Installing deflectors on the Chevrolet Lacetti is not just an aesthetic improvement, but a real need for comfortable driving in our latitudes. Owners of this car often encounter rain in the cabin with a slightly open window, especially when parking or driving at low speeds. Properly selected and well-established wind-breaker This problem is solved by creating an aerodynamic curtain.
Unlike mechanical fasteners, the adhesive method of fixation is considered the most reliable and proven time for the body. Lacetti. It provides a tight fit, eliminates rattling at high speeds and does not require drilling of the body. However, the success of the entire operation depends on the quality of surface preparation and the choice of the correct adhesive.
Many beginners make the mistake of ignoring the temperature regime or saving on a degreaser, which leads to the uncoupling of the elements after a couple of months. To avoid rework and time loss, it is necessary to strictly follow the technology. In this article, we’ll break down all the nuances, from the choice of materials to the final polishing, so that your deflectors last for years.
Choosing quality deflectors for Chevrolet Lacetti
The first step to a successful installation is to buy the right accessories. The market is full of offers, but not all of them are suitable for Chevrolet Lacetti in the body of a sedan, hatchback or station wagon. The geometry of window openings in these models has its own characteristics, and universal solutions "for all cars" will not pass here. It is important to look for products marked specifically for your body modification.
Particular attention should be paid to the material of manufacture. Cheap plastic under the influence of ultraviolet light quickly becomes cloudy, covered by a network of microcracks and loses transparency. Quality plastic Polycarbonate retains its properties for many years, remaining elastic and durable. The thickness of the deflector wall also plays a role: too thin elements can be deformed when heated in the sun.
Pay attention to the mounting system. For the adhesive method, ideal models with a wide adhesive band around the perimeter or with several powerful 3M inserts. Some manufacturers offer a combined option: adhesive base plus insertion into the upper window opening. For Lacetti it is better to choose purely glue options, since the insertion into the opening can violate the sealing of the seal when lowering the glass.
- ✅ Original accessories GM is expensive, but perfect in geometry.
- ✅ Brand analogues (Heko, Cobra, Sim) – the optimal ratio of price and quality.
- ✅ Budgetary Chinese Options It requires a thorough geometry check before buying.
Before buying, be sure to try on the deflector to the window without removing the protective film. The gaps shall be minimal and uniform throughout the length. If you see distortions or mismatch of the radius of curvature with the door, it is better to look for another manufacturer.
Required tools and materials for installation
The quality of the installation depends on what you use in the process. To collect the necessary arsenal in advance, so as not to run to the store in the middle of the process, when the glue has already begun to dry. The main consumables are special primer and double-sided tape, although often it is already applied to the product.
A critical step is degreasing. Use of ordinary alcohol or vodka is not recommended, as they can leave a divorce or contain moisture. The best choice will be a special one. degreaser based on isopropyl alcohol or white spirit. You will also need a soft rag that leaves no pile, and a stationery knife.
To warm up the glue and improve adhesion in the cold season, a construction hair dryer will be needed. A normal household hair dryer may not give the desired temperature, although in the summer heat you can do without it. If you plan to work in the winter in the garage, having a heat source is a must.
☑️ Checklist of instruments
Don’t forget to prepare the workplace. The car should be in a clean, dry room, protected from wind and dust. Getting a grain of sand under the glue base can spoil the whole look and reduce the reliability of the attachment. The temperature in the room should not be lower than +15 ° C, otherwise the glue is not polymerized properly.
⚠️ Attention: Never use acetone or aggressive solvents (646, 647) to degrease the body in the installation area. They can damage the coating of the door. Lacettimaking it matte or even dissolving a layer of paint.
Preparation of the body surface for installation
Preparation is 80% of the success of the whole operation. Even the most expensive glue will not stay on a dirty, greasy or moist surface. First of all, the car must be thoroughly washed, paying special attention to the upper window frames and racks. After washing the body must be wiped dry.
Then comes the deep cleaning phase. Within the windows, the remains of polish, bitumen stains and technical lubricant often accumulate, which is not washed away by ordinary water. Use clay for a car service or a special bitumen cleaner to remove all extraneous inclusions. The surface should be perfectly smooth to the touch.
The final touch of preparation is degreasing. Plenty moisten the napkin with a degreaser and thoroughly wipe the places of future contact of the deflector with the body. Do this in one direction so as not to smear the dirt. After processing don't touch to the prepared places with your hands, since skin fat will instantly reduce adhesion.
If there are chips or scratches on the body in the installation sites, it is advisable to paint them or preserve them before installation. Under the deflector can accumulate moisture, which will lead to corrosion of the metal at the site of damage to the paint. For Chevrolet Lacetti This is especially true because of the design of the door frames.
Nuances of working with the old body
If the car is more than 10 years old, chromium may oxidize or corrosion may appear on the windows. In this case, before installing the deflectors, it is necessary to clean these places with small sandpaper (P2000) and polish. Glued on rust or oxidized chromium can not be - the deflector will fall off along with pieces of coating.
Adhesive technology: step-by-step algorithm
The installation process itself requires accuracy and does not tolerate haste. First, try on all four deflectors on dry, make sure the position is correct. Then we can start the installation. It is recommended to start with the front doors as they have the largest contact area and experience maximum wind load.
Remove the protective film from the deflector adhesive layer. If it is cool outside or the deflector is cold, be sure to warm up the adhesive strip and the place on the body with a building hair dryer to a temperature of 40-50 ° C. Warm glue becomes more elastic and sticky, which provides instant grip. Some masters also recommend heating the adhesive tape itself with a hairdryer before removing the protection.
Carefully apply the deflector to the installation site, focusing on the gaps. Do not press it hard at once - give yourself the opportunity to adjust the position in the first seconds. Making sure that everything is up straight, with effort press the deflector along the entire length, especially in places of applying glue. Move from the center to the edges, expelling the air.
For final fixation, paint scotch can be used, temporarily fixing the deflector in a pressed state for 10-15 minutes until the glue cools and gains primary strength. This is especially useful when installed on side mirrors or curved surfaces.
| Work phase | Temperature regime | Cover time. | Important nuances |
|---|---|---|---|
| Warming up glue | 40-50°C | 30-60 seconds | Do not overheat the plastic before melting |
| Pressure | Above +15°C | 1-2 minutes | Press evenly over the length |
| Primary polymerization | Room room | 24 hours. | Don't wet or slam the door too hard |
| Full operation | Anybody. | 48-72 hours | You can wash your car in the wash. |
The main secret of success is not to rush to remove the protective film from the tape until the moment of fitting, and be sure to warm up the glue before pressing.
Features of installation on different types of body
Chevrolet Lacetti was produced in three types of body, and each has its own characteristics when installing deflectors. Owners. sedans The luckiest thing is that long straight lines of windows allow you to install deflectors the first time without complex fitting. The main thing is to maintain a straight line relative to the upper edge of the door.
Nana hatchback The situation is more complicated due to the steeper inclination of the rear pillars and the complex geometry of the rear windows. Here, more careful heating of the corners is often required so that the deflector does not protrude. Sometimes you have to use an additional primer on the ends, since the contact area in the corners is minimal.
Universals Lacetti Wagon have long rear doors, which creates increased wind load on the rear deflectors. For such cars, it is recommended to choose models with reinforced adhesive layer or additional mechanical fixation, if the design allows. It is also worth paying attention to compatibility with rails, if they are installed.
- 🚗 Sedan: Simple geometry, minimal error risk, classical setting.
- 🚙 Hatchback: It requires attention to the corners, a complex radius of bending is possible.
- 🚐 Wagon: High sailing, maximum adhesion and accuracy are needed.
Regardless of the body type, always check the windows after installation. The glass shall be lowered and lifted freely without touching the lower edge of the deflector. If the glass touches the accessory, it must be immediately dismantled and reinstalled higher, otherwise you risk breaking the glass or damaging the lifting mechanism.
⚠️ Attention: After installing deflectors in the first 24 hours, it is not recommended to open windows and slam doors with great force. A sharp drop in pressure can disrupt the process of primary glue grasping, especially if the room is cold.
Caring for deflectors and frequent errors
After successful installation, you want the deflectors to last a long time and please the eye. However, improper care can quickly lead them to disrepair. When washing a car, avoid using brushes with hard bristles in the area of deflectors. It is better to use a soft sponge or high pressure wash, directing the jet at an angle rather than perpendicular to the edge.
A common mistake is to use aggressive autochemistry to wash the body. Alkaline shampoos and acid cleaners can make the plastic cloudy and whitish. For cleaning, use special polishes for plastic or ordinary soap solution. Periodically (once every six months) it is recommended to treat deflectors with a protective composition with a UV filter.
If you notice that the deflector has begun to peel off in one of the corners, do not wait until it falls off completely. Water and dirt can get into the gap, which will finally destroy the glue layer. At the first signs of detachment, warm up the problem area with a hairdryer and press hard. If this does not help - you will have to remove the element, clean the old glue and glue it again on new tape.
Tip: To polish the dimmed deflectors, use toothpaste or a special paste for polishing the headlights. This will bring transparency back and remove small scratches.
Compliance with these simple rules will allow you to enjoy the comfort of the cabin. Lacetti in any weather. Deflectors are a trifle that significantly improves the level of driving comfort, protecting against rain, snow and insects flying into a slightly open window.
Can I use deflectors in winter in the cold?
It's not recommended. At temperatures below +5°C, most car adhesives lose their properties and do not provide reliable fixation. If the installation is vital, the car should stand in a warm garage for a day, and the process itself should take place at a temperature not lower than + 15 ° C.
How to remove the remnants of old glue when replacing deflectors?
To remove old double-sided tape, it is best to use a special glue remover (for example, Kangaroo or analogue) and a plastic spatula. You can also use a hair dryer to soften the glue, and gently roll it with a finger or rubber roller.
Do deflectors affect fuel consumption?
Yes, they do, but they're not. Deflectors disrupt the aerodynamics of the car, creating additional air resistance. On the track at high speeds, the flow can increase by 0.3-0.5 liters. In the urban cycle, the difference is almost not noticeable.
