Fitting and installation

Professional installation is recommended for the best alignment and bond. For expert fitting, book with MJ Modifications in Warwickshire. Request a quote: info@mjmodifications.co.uk.

Always test-fit before removing the adhesive backing
Thoroughly clean and degrease the contact area to maximise adhesion
Apply firm, even pressure along the full length and allow the tape to cure
Avoid washing the vehicle for at least 24 hours after installation

Material and finish

Material: ABS plastic for strength with a degree of flexibility
Finish: High gloss black

ABS is widely used in OEM exterior parts thanks to its stability, impact resistance and suitability for daily driving conditions.

Authenticity and returns

This is a genuine Maxton Design product. A holographic verification label confirms authenticity. Do not remove the hologram unless you intend to keep the item, as removal will void return eligibility.

Protective film

A thin vacuum-sealed protective film is applied to prevent transport marks. Remove this layer to reveal the gloss finish. Any light marks seen prior to removal are on the film, not the surface itself.
