TONZACK Car Headlight Repair Liquid 800g — Polymer Scratch Remover & UV Protectant for Dull Yellow Lenses

TONZACK Car Headlight Scratch Repair Liquid is an 800 g polymer formula designed to remove scratches, yellowing, and cloudiness from vehicle headlights to restore clear light output and appearance.

If your headlights look dull, yellowed, or scratched, this concentrated repair liquid provides a do-it-yourself option to refresh lenses without replacing them. The formula uses polymer and nano UV components to bond with headlight plastic, improving clarity and adding protection against short-term re-yellowing. It’s sold in a single 800 g bottle that the manufacturer estimates will treat multiple headlights or several vehicles, and it’s suitable for cars, motorcycles, electric vehicles, trailers and marine windows.

How does TONZACK repair scratched or yellowed headlights?

The liquid works by filling fine scratches and smoothing the lens surface, then forming a thin polymer layer that improves optical clarity. It pairs mechanical polishing with a chemical film that adheres to plastic, reducing the appearance of abrasion and oxidation.

• Fills and levels micro-scratches to reduce scattering of light.
• Polymer layer bonds to the lens for a clearer finish.
• Nano UV components help protect against short-term sun damage.

What steps are needed to use this polishing fluid safely and effectively?

Preparation and proper technique matter: clean the lens, apply the liquid according to product instructions, polish with appropriate pads, and avoid direct sunlight while curing. The product instructions recommend wearing a mask and storing the bottle in a cool, dry place away from sun exposure.

• Clean surface of dirt and grease before application.
• Use a polishing pad or cloth to work the liquid into the lens evenly.
• Let the polymer film cure and avoid prolonged sunlight during storage.

Which vehicle parts and materials can this repair liquid be used on?

TONZACK’s formula is intended primarily for plastic headlight lenses but is also compatible with taillights, motorcycle lights, trailer lights and certain boat windows. It’s not a universal fix for all materials, so test on an inconspicuous area first if you’re unsure of the substrate.

• Automotive polycarbonate and acrylic headlight lenses.
• Motorcycle and electric vehicle headlight and taillight plastics.
• Trailer lights and some marine glazing with similar plastics.

How many uses will one 800 g bottle deliver, and what care is required?

An 800 g container is sized to cover several treatments — typically 3–4 full headlight restorations depending on lens size and damage level. For long shelf life, keep the bottle sealed and stored out of direct sunlight; the product is formulated without heavy metals and aims to be environmentally mindful.

• Estimated 3–4 full uses per bottle under typical conditions.
• Store sealed in a cool, dry place away from sunlight to avoid degradation.
• Recommended to keep protective gear on during application (mask, gloves).

It suits people restoring older vehicles, maintaining motorcycle or trailer lights, or anyone seeking a polymer-based repair that combines polishing with protective bonding.
