📦 Kit Contents
1. Polyurethane Sealant APP PU 50 FC BLACK — 310 ml Cartridge
The most critical component of the assembly. The APP PU 50 FC BLACK is a single-component fast-curing polyurethane sealant that we use and recommend for our covers: excellent adhesion to the polycarbonate (PC) of the cover, the black paint and the ABS base of the headlight unit — it bonds perfectly to all these materials.
This sealant is the result of extensive comparative testing with multiple products available on the market. After numerous trials, it proved to be the best because it offers the perfect balance between bonding strength and flexibility: on the vehicle, the covers are constantly subjected to stress and vibrations transmitted by the body during normal road use. Sealants that are too rigid crack and fail over time, while those that are too soft do not guarantee a lasting watertight seal. The APP PU 50 FC BLACK remains permanently elastic after curing, absorbing vibrations without breaking or losing adhesion.
Black colour: the only suitable colour for headlight cover installation. A sealant of a different colour could be visible from the outside through the transparent cover, compromising the aesthetic result.
FC stands for Fast Cure: rapid curing — ideal for those working in a garage or workshop where time matters.

2. Double-Face Microfiber Cloth — Yellow/Grey — Size Small
Two sides, one goal: perfect surfaces without leaving a trace. Cleaning a freshly installed cover with the wrong cloth is one of the most common — and most frustrating — mistakes. The ultra-fine microfiber fibres capture dirt, grease and moisture without rubbing, scratching or leaving streaks.
Unlike a regular cloth, microfiber is made of millions of fibres with a diameter of just 0.4 μm — 1/10 the thickness of a silk thread. These microscopic fibres carry an electrostatic charge (positive-charged polyester and negative-charged polyamide) that actively attracts and captures dust, grease and dirt particles from the surface, trapping them between the fibres without the need for detergents. They don't just move dirt around: they lift it and hold it.
The double-face design doubles its versatility: use the high-absorbency yellow side for deep cleaning, and the smoother, more compact grey side for finishing, polishing and inspecting the final result after removing the protective film.
- Material: double-face microfiber (polyester/polyamide)
- Fibre diameter: 0.4 μm (1/10 of silk)

- Machine washable at low temperature (30–40°C), without fabric softener
- Reusable for dozens of washes without loss of performance
3. White Cotton Gloves — Pair — One Size Medium
The detail that makes the difference between a perfect installation and an unnecessary scratch. You've invested in new covers, prepared everything with care — and then a wrong touch leaves a fingerprint or a micro-scratch on the surface. It's the kind of mistake you prevent with a tool that costs very little but is worth a lot.
White cotton gloves are the standard in industries where surfaces matter: from quality control in electronics manufacturing to jewellery, from photography to optical engineering, from museum conservation to premium bodywork. Cotton doesn't scratch, doesn't leave residue, doesn't mark.
It's not just about aesthetics: the natural oils from your skin, invisible to the naked eye, can over time deteriorate and cloud the polycarbonate surface. Cotton gloves create a complete protective barrier between your hands and the cover, without compromising tactile sensitivity — you feel exactly what you're doing.
- Material: 100% natural twisted-thread cotton
- Colour: white
- Size: one size medium
- Antistatic protection: prevents electrostatic discharge on surfaces
- Lint-free: no cotton fibres left on the cover
- Anti-fingerprint barrier: blocks transfer of natural skin oils
- Soft, breathable, non-abrasive
- Tactile sensitivity maintained for precise handling
- Washable and reusable (hand wash or machine wash at 30°C, without fabric softener)
- Sold as a pair (left + right hand)

❓ FAQ
Q: Can I install the covers without this kit?
A: Yes, it is possible to use your own products. However, the sealant is the most critical component: a product not specifically compatible with the polycarbonate (PC) of the cover, the paint and the ABS of the headlight body could over time lose adhesion, deteriorate the materials or compromise the watertight seal, causing water infiltration and internal fogging. With this kit you have the certainty of using exactly the products we recommend, with verified compatibility on all materials involved.
Q: Why did you choose this particular sealant?
A: The APP PU 50 FC BLACK is the result of extensive comparative testing with multiple sealants available on the market. After numerous trials, it proved to be the best because it offers the perfect balance between bonding strength and flexibility. On the vehicle, the covers are constantly subjected to stress and vibrations transmitted by the body during normal road use: sealants that are too rigid crack and fail over time, while those that are too soft do not guarantee a lasting watertight seal. The APP PU 50 FC BLACK remains permanently elastic after curing, absorbing vibrations without breaking or losing adhesion. It also proved to be the most suitable among all products tested for simultaneous adhesion on polycarbonate (PC), black paint and ABS — the three materials present in the headlight unit.
Q: Why black only?
A: Black is the only suitable colour for headlight cover installation. A white, grey or beige sealant could be visible from the outside through the transparent cover, compromising the aesthetic result. Black blends perfectly with the headlight body.
Q: Is the sealant enough for both headlights?
A: Yes, one 310 ml cartridge is more than sufficient to seal both covers.
Q: Do I need a caulking gun for the sealant?
A: Yes, the sealant comes in a standard 310 ml cartridge compatible with any manual or pneumatic caulking gun. The gun is not included in the kit as it is a common tool already found in most garages.
Q: How long do I have to position the cover after applying the sealant?
A: The product is workable for approximately 15–20 minutes after application, after which it begins to set. We recommend completing the cover positioning within this window.
Q: How does the microfiber cloth work? Why is it better than a regular cloth?
A: Microfiber is made of millions of fibres with a diameter of just 0.4 μm (1/10 of a silk thread). These microscopic fibres carry an electrostatic charge (positive-charged polyester, negative-charged polyamide) that actively attracts and captures dust, grease and dirt from the surface — without the need for detergents. A regular cloth moves dirt around; microfiber lifts it and traps it between the fibres, leaving the surface perfectly clean.
Q: What is the difference between the two sides of the microfiber cloth?
A: The yellow side has a higher, spongier pile: ideal for absorbing moisture and removing dirt and grease in depth. The grey side has a smoother, more compact texture: ideal for finishing, polishing and final inspection without leaving streaks — to be used after removing the protective film.
Q: Why cotton gloves and not latex or nitrile?
A: Latex and nitrile are excellent for chemical protection, but can leave micro-marks on delicate surfaces such as optical polycarbonate. Cotton is the safest material for aesthetic handling: soft, non-abrasive, leaves no residue. Cotton gloves also offer antistatic protection and maintain tactile sensitivity, allowing precise control during cover positioning.
Q: Why is it important to wear gloves and not handle the cover with bare hands?
A: It's not just about aesthetics. The natural oils from your skin, invisible to the naked eye, can over time deteriorate and cloud the polycarbonate surface. Cotton gloves create a complete protective barrier between your hands and the cover, preventing both visible fingerprints and long-term material deterioration.
Q: Can the gloves be used during sealant application?
A: For positioning and trial fitting, yes. During direct sealant application with the caulking gun, some prefer nitrile gloves to prevent the product from soaking into the cotton. For cover handling, they remain the best choice.
Q: Is shipping really free with the covers?
A: Yes, for Italy the Kit shipping is completely free when purchased together with the covers. For international orders, only the cover shipping applies — the Kit adds no additional shipping cost.
