Product Description

The Gtechniq I1 Smart Fabric allows you to protect you interior fabrics (ie carpets, mats, etc.) and exterior (ie convertable tops, outdoor furniture, etc.) from nearly anything life can throw at it! Various areas of your vehicle can become dirty fast, especially fabrics that easily grab and hold dirt and grime. With I1, simply spray your vehicles fabrics and the nanoparticles in this high-quality formula will coat the individual fibers in a protective layer. Water and oil-based liquids are instantly repelled from the surface, that means coffee, wine, soda, blood, and more will simply roll off the surface! Wipe away any spills with a damp cloth and you will be left with zero staining! Apply I1 to your convertible tops, fabric seats, carpets, mats, outdoor furniture, shoes, clothing, and more. Best yet, the fibers remain breathable and feel soft and flexible. No sticky or plastic feeling from this formula. If you are looking for some antibacterial features, check out the I1 AB. If you are looking to protect your fabric surfaces, check out the Gtechniq I1 Smart Fabric!

V2 Formula:
  • V2 is more durable, hydrophobic, and a has moved away from fluorocarbons to a more environmentally friendly formula than V1.

I1 vs I1 AB:
  • I1 - Protects fabric surfaces and is highly recommended for use on convertible tops, boats and exterior fabrics.
  • I1 AB - Protects fabric surfaces but also features BioCote, which is an antimicrobial technology that helps kill 99.9% of the bacteria on the surface. The AB properties can cause a "dust" when over applied, so avoid application on convertible tops, boats and exterior fabrics. For these areas, use the regular I1.

Professional Detailer Reviews

The hydrophobic properties are amazing! The I1 Smart Fabric still allows the material to breath and does not take away from the natural texture what so ever. Durability will depend on the amount of use obviously and will require re-application as needed.

Although pricey, Gtechniq I1 is still my preferred choice for floor mats, which would otherwise be easily soiled without protection. V2, the latest formulation of the product, was a major improvement. I've tried Carpro cquartz Fabric and Gyeon Q2 but neither of them provided the same protection and longevity as I1. To get the best results, be sure that what you want to protect is completely dry. Beware that the fumes are very strong. However, the smell dissipates quickly once the solvents have flashed.

I bought this on a recommendation from a friend. I treated the seating surfaces of my 2019 Ranger XLT and the carpeting.

Pros: it repels water and other liquids very well
Cons: it has a strong "aroma" that takes time to air out.

Another use for Smart Fabric is on the fabric fender liners found in most cars today.. it makes them easier to clean.

IMPORTANT - I used the v2 formulation (May 2018). Incredible water beading for my convertible top! I cleaned well with CarPro Reset, and nothing else. Let the top dry thoroughly. Shook well, and sprayed liberally all over. Before it could dry, I hit it again with a second coat. Let air dry for about 24hrs.

It's been about a month since I applied. I wash my car weekly. It poured down rain for about 6 hours yesterday and when I walked out of the office, my top was still beading like it was when the rain started. Amazing product!

I have used the 303 convertible top cleaner/sealer in the past, and this is 100% better. If I could post the images of the beading yesterday, I would, because I couldn't believe it! Great stuff!

Also, for prep, I didn't tape anything off this time, as I usually would with the 303 products. The over spray on the convertible top window, side windows, and windshield was easily removed the next day with Stoners Invisible Glass. The tiny bit that got on the paint came off with CarPro EcH2O diluted into waterless wash. There was no staining on the rubber around the convertible top.

Super easy and excellent results! Will use this stuff on the top annually now, and all my carpets/floor mats!
