Gtechniq's latest V3 version of I1 Smart Fabric delivers the same incredible hydrophobic properties as before, with the added benefit of anti-mould and anti-mildew technology. I1 Smart Fabric also protects against long-term fabric degradation from UV rays and general wear.

Laboratory tests have shown version 3 of Gtechniq's I1 Smart Fabric to last 4 times longer than the closest competitor on the market.

Gtechniq I1 Smart Fabric makes ordinary fabrics waterproof and easy to clean. Use it to prevent soaking, swelling or rotting on any fabric. Ideal for use on your cars convertible roof or interior.

Smart Fabric is colour safe. Nano particles that make up I1 Smart Fabric coat each fabric fibre individually, leaving the texture unaffected, allowing the material to breathe. This means stale air will still be able to escape, while repelling water and and oil-based liquids. Gtechniq I1 Smart Fabric protects all kinds of fabrics from water-based stains. It is breathable and extremely durable, thanks to Gtechniq’s unique scientific formula.

On average, I1 will last on a car’s interior for between 6 and 12 months - depending how ‘used’ the surface is. On convertible roofs the product will last for up to 2 years.
