Removal of factory or additional emblems from the trunk lid begins with an assessment of the type of fastening and condition of the paint coating. If the nameplate is held on double-sided tape, its edges often bend over time, creating an ideal entry point for the tool, and in the case of a hard landing on the adhesive sealant, preheating of the surface to 60-70 degrees will be required. Incorrectly chosen method of dismantling, for example, a sharp force effect without warming up, can lead to detachment of the paint along with the decorative element, especially on cars with an age of more than 10 years.
Before starting work, you need to prepare a desktop with tools, as the process requires concentration and lack of haste. The main enemies when removing are dirt, which can scratch the LCP when rubbed, and remnants of old glue, which cannot be removed without special solvents. The correct sequence of actions allows you to maintain the integrity of the body and avoid expensive local painting in the future.
Necessary tools and preparation of the work area
The qualitative result directly depends on what exactly you plan to influence the adhesive base of the emblem. For careful dismantling will require a specialized set, including hair dryer with temperature adjustment, allowing you to gently heat the adhesive layer without damaging the plastic or chromium of the nameplate itself. The use of open fire, for example, lighters, is strictly prohibited, since local overheating can deform the trunk lid or leave indelible traces of soot.
In addition, you will need a thin fishing line or a special string to cut glue, as well as a set of plastic blades to wipe off the remnants of the mass. The chemical industry offers a variety of glue-removerswhich effectively dissolve polymeric compounds, but require careful handling of rubber seals. Do not forget about microfiber and degreasing, which will be the final stage of surface preparation.
β οΈ Warning: Before using aggressive chemicals, be sure to test the product on an inconspicuous area of the body to exclude a reaction with varnish or paint.
Mechanical method of removal by heating
The most common and safe way of dismantling is thermal exposure, which softens the cool base. Direct the jet of hot air evenly over the entire surface of the nameplate, moving the hair dryer from side to side to avoid the point of overheating. The process usually takes 2 to 5 minutes depending on the thickness of the metal and the type of adhesive, after which the emblem should be easily mechanically affected.
After sufficient warming up, gently tuck the edge of the label with a plastic spatula or nail, trying not to use metal objects. If the element sits tightly, do not put excessive effort, and add a little more heat, because glue It becomes stained and can stain the adjacent parts of the body. Gradually increase the amplitude of movement, separating the emblem from the surface of the trunk.
It is important to control the surface temperature with your hand: if the metal becomes too hot to touch, pause. Sharp cooling is also undesirable, so work is better carried out in a warm garage, not in the cold, where the temperature difference can lead to microcracks of the varnish.
Use an infrared thermometer to monitor surface temperature. The optimal range for softening most automotive adhesives is 60-80Β°C.
Using thread and fishing line for a neat cut
The method of cutting the adhesive layer is often used in combination with heating or as an independent procedure for old, dried emblems. Take a thin but strong fishing line or a special string, wind the ends on your fingers or wooden handles for ease of grip. Get the thread at one of the upper corners of the nameplate and move it down with sawdling movements, trying to keep the line as parallel as possible to the surface of the body.
This approach allows you to physically separate the decorative element from the base, leaving the main layer of glue on the body, which simplifies subsequent cleaning. Movements should be smooth, without jerks, so that the line does not crash into the paint coating and does not leave deep furrows. If the nameplate has a complex relief shape, use a thin mediator or plastic card to help in hard-to-reach places.
- π§΅ The line should be thin (0.2-0.3 mm) to minimize friction against the body.
- π₯ Preheating significantly reduces the force required to cut.
- π§€ Work with gloves so that the line does not cut the skin of the fingers when stretching.
- π Keep the angle of attack of the line sharp, almost pressed to the surface of the trunk.
Chemical solvents and surface cleaning
After the physical removal of the nameplate on the surface of the trunk will inevitably remain traces of glue, which require chemical exposure. Automotive Chemistry offers specialized bitumen-spot removerwhich effectively cope with polymeric residues. Apply the product to a soft rag or microfiber and apply to the contaminated area for 30-60 seconds so that the active components begin to dissolve the glue structure.
Do not rub the surface with dry glue, as you risk simply smearing the sticky mass over a larger area. After softening, gently roll the glue residues with a finger or plastic spatula into the coils, which are easily removed. For final processing, use isopropyl alcohol or a special degreasing agent that will remove the fat film and residues of chemistry.
| Type of instrument | Efficiency | Safety for LCPs | Exposition time |
|---|---|---|---|
| White Spirit | Medium | Tall. | 2-3 minutes |
| Specialized adhesive remover | Tall. | Medium (requires flushing) | 30-60 seconds. |
| WD-40 | Low/Mediocre | Tall. | 5-10 minutes |
| acetone | Very high. | Low (may damage the varnish) | Instantly. |
Polishing and restoring the trunk cover
Long-term presence of the nameplate creates on the body a site protected from burnout and microscraps, so after its removal, a difference in shade or βstepβ may appear. If you plan to leave the trunk without emblems, it is recommended to conduct a light abrasive polishing of the entire plane of the lid to level the transition and remove the boundaries of burnout. Use of the polishing medium abrasiveness will help to remove the micron layer of varnish and refresh the color.
In case corrosion or chips formed under the nameplate, more serious repairs will be required using corrosion-resistant soils and local paint. Often, moisture accumulates under the emblems, which does not evaporate for years, leading to the oxidation of the metal, so a careful examination of the surface that has opened is mandatory. If there are no defects, it is enough to apply protective wax or ceramic coating for uniform shine.
Donβt ignore this stage, as the contrast between the βyoungβ color under the nameplate and the burnt out around can be striking, especially on dark cars of red or blue hues. The polishing will also remove possible micro scratches obtained during the process of dismantling the fishing line or tool.
What to do if there is a βstepβ left?
If the nameplate stood for a very long time, under it the layer of varnish could be thicker or, conversely, thinner due to the peculiarities of the factory coloring. In most cases, light abrasive polishing (step 1 or step 2) removes the elevation difference. If the step is felt by the nail, it may be necessary to remove some of the varnish around or, in rare cases, local repainting of the element.
Typical errors and precautions
One of the most common mistakes is to try to pick the badge off with a screwdriver or knife without first heating. This barbaric method is almost guaranteed to leave deep scratches on metal and plastic, the elimination of which will require professional polishing or even painting. Metal tools shall be excluded from the external bodywork.
Another common problem is the use of aggressive solvents such as acetone or 646th solvent, which can βliftβ the varnish, make it cloudy or change the color of the plastic. Always read the instructions for the chemical and make sure it is safe for car enamels. Also, do not rush and try to tear the emblem with a jerk until the glue is heated to the desired temperature.
- β Do not use metal blades to tweak the edges.
- β Do not pour solvent directly on the body, only on the napkin.
- β Donβt ignore the chemical protection of rubber seals.
- β Do not work in direct sunlight, so that the chemistry does not dry out instantly.
β οΈ Note: If the nameplate has through legs passing through holes in the body, its removal may violate the tightness of the trunk. In this case, additional treatment of the holes with sealant will be required.
βοΈ Checklist before kick-off
FAQ: Frequently Asked Questions
Will the holes remain after the nameplate is removed?
Factory emblems are often attached to double-sided scotch and do not have through holes. However, some models (e.g., individual letters or logos) may be fixed through holes in the metal. In this case, after removal, sealing of the holes with body sealant, primer and painting, or installation of a universal plug will be required.
What is the best way to wipe off a black sticky trail?
It is best to use specialized products labeled "Remover" or "Kleber Entferner". They are designed specifically for automotive adhesive bases. Alternatives include WD-40 or isopropyl alcohol, but these require longer exposure times.
Can I remove the nameplate in winter in the cold?
It's highly discouraged. In the cold, the plastic becomes fragile and can burst during dismantling, and the glue does not soften even when heated with a hair dryer, since the metal quickly gives off heat. In addition, the temperature difference can lead to the appearance of microcracks on the varnish. It is better to carry out the procedure in a warm room.
How to hide a place where the nameplate was, if you do not want to polish?
If polishing is not possible, you can install a new emblem, palisade or decorative overlay. There are also universal stickers-stubs, selected in body color, which cover the traces of installation or holes.
The secret to success is patience and quality heating. 90% of the problems with removal occur due to insufficient temperature of the glue before the start of mechanical action.
