Silicone Spray

Silicone spray is a lubricant and protectant used on rubber seals, plastic guides and sliding parts to reduce friction and repel water.

What is Silicone Spray?

It keeps door and boot seals supple and helps stop them freezing shut. It eases sticky window channels and sunroof guides where the manual allows. It does not attack most rubbers and plastics. Treating seals in autumn helps prevent doors from freezing shut in winter.

How it works

A thin silicone film reduces friction and forms a water-repellent layer.

Why it matters for your car

Keep it away from brake parts and from paint that will be repainted, as silicone causes paint defects. Do not spray it on the windscreen or wiper blades.
