Description
Clarity. Hydrophobic Precision. Uncompromised Vision.
Forged for Absolute Clarity, SENTINEL OPTIC is a premium glass coating engineered with Silicone-Based Conditioning Technology to deliver exceptional hydrophobic performance and enhanced protection across glass and mirror surfaces.
Its advanced formulation creates a highly water-repellent surface that causes rain and water droplets to bead, roll away and clear from the glass with ease, helping maintain clearer visibility in wet and demanding conditions. By reducing water retention on the surface, SENTINEL OPTIC helps minimise the visual interference caused by rain, grime and road spray.
When wipers are engaged, the ultra-slick coated surface allows them to glide smoothly across the glass, helping reduce friction and wear while supporting longer wiper service life.
Designed for versatility, SENTINEL OPTIC is suitable for front, back and side windows, exterior and interior glass and mirror surfaces, delivering consistent hydrophobic protection and crystal-clear visibility wherever it is applied.
Built for drivers who demand clarity, control and confidence, SENTINEL OPTIC stands as an invisible shield against rain, water and everyday road grime – helping keep your vision sharp when the elements strike.
Repelling Water. Protecting Clarity. Commanding The Road.
APPLICATION
- Clean all windows & windshield surfaces using Sentinel RELEASE (pH Neutral Shampoo). For any stubborn contaminants, gently use the provided Soft Foam Sanding Sponge with plenty of soapy water, ensuring the surface remains lubricated. Take care not to touch adjacent paintwork or trims with the abrasive pad.
- Rinse thoroughly and dry with a microfiber towel or blower if available.
- Wipe all surfaces with the provided Sentinel CLEANSE (Panel Wipe) to eliminate any oils or residue left from washing. Be sure to use a clean microfiber towel for this task.
- Begin applying the coating to all side windows, then the rear windshield, and finally the front windshield.
- Generously apply SENTINEL OPTIC to the applicator cloth using the applicator block, making sure to cover the area fully and evenly by applying in all directions. When the coating begins to “sweat” and displays a “rainbow” effect, buff it lightly with a clean microfiber towel.
- In warmer temperatures, drying times are shorter, so be sure to buff the coating sooner to prevent cloudiness.
- Do not apply too much coating onto the front windshield to prevent wipers from squeaking.
- Repeat this application process on adjacent areas until all windows & windshields are coated.
- Allow the coating to cure completely for at least 2 – 4 hours with full curing achieved in seven days.
- During the curing period, you may lightly clean the surfaces with a clean microfiber towel when the surfaces are wet.
- After 6 months, you can optionally apply the second layer of SENTINEL OPTIC, depending on remaining product.
AFTERCARE & MAINTENANCE
- After washing with Sentinel RELEASE (pH Neutral Shampoo), rinse the surfaces thoroughly.
- Avoid using harsh chemicals or low-quality soaps or shampoos.
- Dry the surfaces with a clean microfiber towel.
Adhering to the Aftercare procedures can extend the protection to last up to 2 years and beyond.
TIPS
- If using the last of the coating product, focus on the side windows.
- Use the Soft Foam Sanding Sponge solely for removing stubborn contaminants, ensuring you apply plenty of water. You can keep the sponge for future use.
- Use with plenty of water when using the Soft Foam Sanding Sponge.
- Avoid using the Soft Foam Sanding Sponge on the two side rear mirrors.
- Buff the surfaces with a fresh microfiber towel.
- Discard any microfiber towels used for buffing the coating. The fibres can become sharp and damage surfaces if reused, even after washing.
PRECAUTIONS
- Use personal protection equipment (gloves, safety glasses, mask).
- Keep out of reach of children.
- Do not ingest. Seek medical advice.
- Avoid prolonged contact with skin.
- Store out of sunlight and in a cool dry area.
- Do not use in conjunction with other products.











Simon M –
Optic leaves the windscreen so smooth the rain is dispelled efficiently and wipers may not be necessary. I love the hypnotic way the water runs down the screen when sitting at traffic lights!
