This new surface protectant from Airglide was developed for the aviation industry, designed to smooth surfaces at a microscopic level and make them slip through the air more efficiently. They even use it on wind turbine blades, and your car can benefit from the same tech.

Ultimate Shield is an easy-to-apply, two-part system that can go on everything, from tyres to glass.

The first product deep cleans the surface, removing any deposits and dead paint cells in the pores, creating a flexible shield with a negative charge. The second part fills the pores and creates a micron-thick barrier that’s positively charged and perfectly smooth.

Basically for your car it means, for want of a technical phrase, dirt won’t stick to it.
