Reactive Polymer Protection
FLEX uses reactive polymer technology to leave behind a durable protective layer across the treated surfaces.
Once rinsed and dried, this layer helps improve:
- Surface slickness
- Gloss
- Water behaviour
- Resistance to everyday contamination
Deep Gloss Finish
One of FLEX’s main benefits is its ability to enhance the appearance of the paintwork.
After application, the surface is left looking:
- Deeper
- Glossier
- Cleaner
- More freshly detailed
This makes FLEX useful for both routine maintenance and show preparation.
Hydrophobic Coating
FLEX creates a strongly water-repellent finish across treated surfaces.
Water is encouraged to move away in two ways:
- Beading
- Sheeting
This helps reduce standing water and can make future maintenance easier.
Water Beading
On treated surfaces, water can form tighter, more defined beads.
This provides both a visual indication of protection and improved water repellency.
Water Sheeting
FLEX also helps water move off larger sections of the vehicle rather than remaining flat across the surface.
This can make:
- Final rinsing
- Drying
- Maintenance washing
quicker and easier.
6–8 Weeks Durability
On a well-maintained vehicle, FLEX can provide around 6–8 weeks of protection from a single application.
Actual durability can vary depending on:
- Mileage
- Weather
- Wash frequency
- Preparation
- Storage conditions
- Application technique
Around 20 Applications Per Bottle
FLEX is highly economical when used at the recommended dose.
Each application uses approximately:
- 5ml FLEX
- 250ml water
At this rate, one bottle provides around:
- 20 applications
This makes it a very cost-effective way to maintain regular hydrophobic protection.
Excellent Cost Per Application
At the quoted usage rate, FLEX works out at approximately:
- 75p per application
This makes it particularly attractive for:
- Regular maintenance
- Multi-car households
- Enthusiasts
- Professional detailers
Suitable for Paintwork
FLEX can be applied across painted exterior surfaces as part of the final protection stage.
Typical areas include:
- Bonnet
- Roof
- Doors
- Wings
- Bumpers
- Boot lid
Suitable for Exterior Glass
FLEX can also be applied across exterior glass.
This helps improve water behaviour on:
- Windscreens
- Side windows
- Rear glass
- Panoramic roofs
Apply to a Wet Vehicle
FLEX is designed to be applied after washing while the vehicle is still wet.
There is no need to fully dry the car before application.
A typical process is:
- Wash the vehicle.
- Rinse thoroughly.
- Leave the exterior wet.
- Apply FLEX.
- Allow to dwell.
- Pressure rinse thoroughly.
- Dry the vehicle.
Easy Snow Foam Lance Application
FLEX is applied using a snow foam lance.
This provides fast and even coverage across the entire vehicle, helping reduce application time compared with hand-applied sealants.
How to Use Duel Autocare FLEX
- Measure 5ml of FLEX using the supplied measuring cup and syringe.
- Add the product to 250ml of water in your snow foam lance bottle.
- Apply evenly across the wet vehicle exterior, including suitable glass surfaces.
- Allow approximately 4–5 minutes of dwell time.
- Do not allow the product to dry.
- Pressure rinse thoroughly.
- Dry the vehicle.
- Rinse the snow foam lance thoroughly after use.
Do Not Allow to Dry
FLEX should never be allowed to dry on the vehicle.
Always monitor the product during dwell time and rinse thoroughly before it begins to dry.
Avoid Direct Sunlight
Do not use FLEX in direct sunlight or on excessively hot panels.
For best results:
- Work in the shade
- Apply to cool surfaces
- Keep dwell time controlled
- Rinse thoroughly
Rinse the Snow Foam Lance After Use
Because FLEX is a polymer sealant, the snow foam lance should be rinsed thoroughly after application.
This helps remove residual product from the lance and internal components.
Always flush the system with clean water before storing it away.
Ideal for Maintenance Protection
FLEX is particularly useful when you want quick protection without spending extra time applying wax or sealant by hand.
It works well for:
- Weekly washes
- Fortnightly maintenance
- Winter protection
- Daily drivers
- Show cars
- Multi-car households
FLEX vs Traditional Sealant
Traditional sealants may require:
- Dry paintwork
- Hand application
- Longer application time
- Buffing
FLEX instead offers:
- Wet application
- Snow foam lance coverage
- Fast rinsing
- 6–8 week protection
This makes it particularly convenient for regular use.
