I1 Smart Fabric Protection for Cars, 500ml

I saw this recommended in Auto Express and gave it a try on my MX-5. Easy to apply and incredibly effective - water just beads up on the roof and lasts for up to a year when garaged at least. Just make sure you cover the windscreen before applying, I didn’t first time and caused awful smearing in rain (think RainX if you ever had the misfortune of trying that!) and ended up changing the wipers. Otherwise fantastic.

Works well when applied in multiple coats. It says a single coat will do - and it does. but I recommend two coats for best results. 1) clean the fabric with a hoover and brush to remove all the debris 2) spray the item in even layers from a distance away from the material to allow even spread 3) repeat step 2 when the first coat has dried. Thats how I get good results. The longevity and durability is pretty good. There is a fairly bad scent when spraying but once dried it is absolutely fine.

After being underwhelmed with the Porsche branded waterproofing spray on my Boxster roof I searched for an alternative. I saw this used by a trusted YouTuber I follow so thought I’d give it a try. Firstly it’s much easier to apply than the Porsche one as it’s a spray bottle rather than an aerosol. After thoroughly cleaning, drying (allow at least 24hrs) and vacuuming the room I gave the roof several coats of this product. I did mask the immediate area of the car roof with some cheap plastic dust sheets just to keep any product off the bodywork. I then put the car in the garage and let it dry out for a couple of days. The performance of this product is simply astounding compared to the Porsche branded waterproofing spray. The water beads really well and runs away quickly. Great stuff and I won’t now be using anything else

This product is very good and surpasses the performance of Renovo, a product I have used in the past with good results. However GTECH last longer and repels water more effectively. Only challenge I had with it is the process of applying it, whereas Renovo you paint it on and the drying process is circa 1 hour to touch dry, GTECH has to be sprayed and becomes sticky in minutes. To compensate and in line with the instructions I soaked the fabric (over did it!) which resulted in some white marks on the fabric. So it takes practice to use, hence in recent past I have used Renovo which is easier apply. Will use it again but will apply less per covering and do a couple of coverings which of course is time consuming and extends the process - weather implications, etc.

Great product as always from gtechniq. Used it before on my previous car to great effect and just used it again on my new Kia sportage gt line s seats and carpets. Tricky application with my seats due to small areas of Alcantara right next to large areas of leather that I was scared to get this product onto for fear of damaging the leather. Try different ways of masking off the leather but then just covered it up with microfibre cloths and sprayed the Alcantara liberally followed by wiping the leather down vigorously with Gtechniq microfibre zero scratch cloths. Then followed by a wipe down with gtechniq tri clean to be sure nothing was left on the leather.. Had a great results no damage to the leather at all and to be fair I don’t think I needed to do the final step with the tri clean. The product wiped off areas not to be treated very well, but I just wanted to go the extra yard. All in all an excellent product to use on interior fabrics of motor vehicles and also home furnishings I would expect so long as you test it first in an inconspicuous area… 10 out of 10 would highly recommend

Lots of solution needed to cover mats and upholstery. I couldn’t see a guide when purchasing but after using it, one bottle is needed for each application and it suggests it needs reapplying yearly or earlier. Upon a water test, water beads well.

Works well and easy to apply

Absolutely fantastic for my soft top convertible. Water beads when it’s been raining. I therefore know the roof has some sort of protection.

Recently purchasing an explorer st and with having 3 kids i’ve gone on a bit of a protection kit buying any product I can to protect it. Having suede seats i was especially worried until i came across this product. It was incredibly easy to apply and the water beading is incredible! It’s been extremely effective against all spills without leaving any residue or leaving any shiny marks where it’s been applied. It has lasted extremely long for me while being on the pricier side i am extremely happy with how long it has lasted i think it’s worth every penny!

Parfait pour toit décapotable.

Very expensive for such a small bottle, not enough to proof more than 1 m . Very disappointed.

This is a great fabric protection product. While costly, I think it's worth it as it doesn't stain or discolor, leave a residue I can feel, or an odour. It is smelly during application, but that fades within a few hours as I aired out the car. Watch online detailing tutorials to see how best to apply this product.

Easy to use.
