Exceeded all expectations. My car is very happy!
This stuff has saved my old tired Saab’s roof. Unfortunately I don’t have a before photo but it looks almost brand new now. Before using this any heavy rain would leave the roof and the liner completely soaked through and water would be literally dripping in at all the door rubber seams, but after one coat of this, the water is sitting on top even after a while of being there. It doesn't seem to even be soaking in over time which was a surprise to me. I jet washed and dried the roof and then applied this just using a paintbrush and making sure I really scrubbed it into the fabric weave and properly soaked any seams and creases where water could collect. It took about an hour/hour and a half and was completely dry after about 4 to 5 hrs (on a sunny warm day). It also improved the colour and made it darker and more consistent. I didn’t have massive expectations for this product because of how bad my car’s leaking was and however long it lasts remains to be seen but so far it’s been totally worth the effort. Some small cons: 1) The smell. It’s VERY strong, i was applying outside with a breeze and still had to take breaks away from the car while painting and had a headache/watery eyes afterwards. And the smell inside the car once it was dry was very strong too but soon faded with windows left open/air con. 2) The liquidyness. This is good for absorbing into the fabric and obviously works but it does make spreading it around hard work (scrubbing to lather it up work it across the fabric worked best for me) and I went through much more than I imagined I would. I only had a small amount left in the can at the end so it was enough for one full coat but only just!

Superb waterproofing for fabric etc
Fabsil Gold in the litre tin, with the microscopic writing, magnifying glass required. Fortunately the info one actually needs is just a few icons; clean and dry the surface, brush on the Fabsil generously, wipe off any surplus and let it dry fully. We have a couple of very nice tough-dense-fabric covered suitcases that have lasted for years and done hundreds of thousands of miles, but recently and unusually the contents became soaked in one case and damp in the other after being caught in the rain, when standing in a seemingly endless queue. Two new “waterproof” Goretex (really?) jackets also let us get wet, not happy. Everything looked clean and unmarked, certainly not greasy or grubby, and it would be a major effort to wash and dry it all. So I took a chance outside on a sunny afternoon, with a new paintbrush, an old aerosol-top-cover as a paint-can, and two hours later after painting/soaking two cases, two jackets, and four pairs of boots, I still had some left for touch-up on zips and seams next day after the first proofing dried, ie also no longer ponging. Two weeks and some very wet weather later, the cases just shrugged off torrential rainwater in beads and remain dry going between car and hotel, and the jackets and boots have performed better than when new. I’ve used original Fabsil over many years, but this was my first try with the Gold concentrate. Success.

I have a lot of waterproof stuff like GoreTex and so on
I have a lot of waterproof stuff like GoreTex and so on. Over time this waterproofing naturally fades and so rather than buy new clothing, I decided to try this. I have used other waterproofing liquids before which require being activated by putting through a hot wash or ironing. I found this never really worked. Fabsil is a whole new level of performance. I painted it on with a regular brush. It's a bit smelly so would recommend doing outside (if it's not raining!). I put on two coats and my hi viz jacket, make of polyester, was back to it's new condition for waterproofing. I'm now going through all my old waterproof stuff and covering it with this. It works really well and is simple to use. I was considering the lesser version of this, but am glad I went with Gold in the end. It's worth the extra bit of money and with the amount of liquid you get, you can go through all your clothes and reprotect them, and still have lots left over. This makes it really good value and better than other types of water reproofing products you can get.

Not the best solution for polyester outside seat cushion covers
When some garden furniture cushions succumbed to mildew, the polyester covers were taken off and I tried various methods of removing the bad staining. White vinegar was useless and in the end I resorted to using a highly concentrated solution of partly dissolved washing powder (not liquid - that didn't work either), dunking the covers in this and leaving them to soak overnight. This did the trick brilliantly, but also removed all the water-proofing from the covers. There were 5 substantial seat cushion covers and 3 smaller back cushion covers to be treated. It required the whole 1 litre tin of Fabsil Gold to do the waterproofing. It was not a pleasant process brushing the product onto each surface of the cover, even though I'd created a couple of rigs in the garage to support the covers while they were being treated. The fumes were pretty strong as well, so not good for a job that took me several hours. It's also been 2 days since the treatment was applied and the covers are still giving off fumes - I've been hanging them on the washing line each day to try and de-fumigate them. HOWEVER, the actual waterproofing is fantastic, so no complaints and full marks for that. If I needed to do it again, I'd buy a 2.5 litre tin of the Fabsil Plus (about the same price as 1 litre of the Gold), put it in a large bowl and just dunk each cover in turn into this less concentrated solution so they're fully wet all over. I'd then suspend each wet cover above the bowl to let it drain before hanging out to dry. To my mind, this would be so much easier. Follow-up comment. Within 5 days of applying the waterproofing liquid and having allowed the covers to air, there's no longer any fumes being given off and no residual smell. An excellent final outcome.

Perfect for waterproofing fabrics of all types
I've used this to recoat waterproofs, garden sofa cushions and soft furnishings and also to recoat my convertible soft top roof. It lasts a long time and has always given good protection against medium to heavy downpours on all my waterproofs. The water beads nicely and rolls off under a light shower. If using on a convertible roof, make sure you wash and clean the roof properly and remove all algae build up and allow to dry completely before coating with Fabsil. It lasts over 12 months but like to recoat outdoor fabrics in the autumn to keep the fabrics at their best. Don't bother with other products to protect your soft top, I've tested them all, Fabsil works the best and lasts the longest.

Great for an aging VW Golf Cabrio reproofing.
In early December I bought a 2015 Golf 2.0 Diesel Cabrio. It had been for sale in Scotland for a couple of months which were mainly very wet. When I took delivery locally it was also very wet and the roof fabric, whilst not leaking was holding a signicant amount of water and needed some attention. Reading up on how best to do this I came across an Amazon review by contributor 'Camelspanker' on 21 June 2018. recommending using Fabsil Gold. I followed his method using Johnsons Baby bath liquid in 5 litres of warm water, I also added a short measure of Milton to this as a means of sterilising/neutralising any mold etc spores. The hood had dried off in my garage before I started and using a soft brush it was easy to work up a good lather which I left in place for a while before thoroughly rinsing with clean water from a hose. Any small spots of green algae can be easily also taken off with a toothbrush and dilute milton, rinse again and when all dried off the Fabsil Gold can be applied. I was fortunate as february was not too cold and pretty dry. I applied the Fabsil Gold outside starting with shaking the can and pouring the contents into a flat bottomed plastic container as required. I used a new 2 inch synthetic bristle brush and painted the fabsil on generously in sections, keeping a wet edge available to work on from. It was pretty straightforward but make sure you have wipes available for stray splashes on windows or bodywork. If left to dry they can be stubborn to remove. I used about 3/4 of a litre of the Fabsil, also when applying make sure you give the seams and fabric 'gutters' a good coating too. and after two days I gave it a good watering from the hosepipe spray nozzle and was delighted to see excellent beading on top/sides of the fabric and no obvious absorption. By all accounts this treatment should last a good 6 to 12 months and hopefully in my case will help the hood last a few more years before needing replacement. This product certainly seems better than ordinary Fabsil and given the benefit, seems well worth the price, it also seems to have refreshed the hood appearance.

Waterproofing Audi A3 soft top
After reading dozens of reviews and car detailing websites I finally settled on the Fabsil Gold to waterproof the soft top of my Audi A3 to get it ready for winter. Some people say not to use it on a soft top but more people said you could than shouldn’t. The roof was cleaned with Renovo first and left to dry thoroughly. I followed the instructions exactly and painted the Fabsil on and left to dry from about 11.00am. Clear, bright and relatively warm autumn day. It rained during the night and absolutely no beading whatsoever. The roof was wet through. I dryed the roof with a hairdryer on a low heat thoroughly so that it was bone dry. Clear sky. No rain. This time I sprayed the Fabsil on, and wiped the roof with a clean dry cloth. Then I got out the hairdryer again until it felt dry to the touch. It rained the next morning and the water beaded off. Brilliant! Two weeks later and it’s tipping it down and the water is just rolling off the top. Not sure why it didn’t work the first time, maybe too much Fabsil and wetting out? But I’m very happy with the second result. I’ll update in a few months when we’ve had a lot more rain.

Easy to apply, plenty of coverage and barely noticeable impact on colour.
Easy to apply with a brush onto campervan pop top roof canvas. The canvas was red and this was painted along the end seams and stitching due to previous leaks at these points. The packaging warned that there might be some colour change when applied but I was really pleased that when it was dry you had to really be looking for the colour difference to notice it as it was very subtle. In regards to waterproofing, I have not yet had the opportunity to test it as it has not rained when in use yet. However, I am confident that it will do a good job as this stuff came highly recommended from a camping group I am a member of. The tub is huge and only a little is needed so the listed coverage should be achievable making it good value for money.

Dla mnie to najskuteczniejszy impregnat do dachów kabrio.
Zdjęcia po ponad 2ch miesiącach od impregnacji, całej nocy na deszczu a co najważniejsze samochód był myty conajmniej raz w tygodniu na myjni bezdotykowej. Żaden inny impregnat tego nie wytrzymywał.

Excellent produit !
Utilisé sur une toile de tente respirante :celle-ci a retrouvé une première jeunesse. Résultat bluffant:j'ai pu vérifier l'étanchéité la semaine qui suivie l'application du Fabsil Gold: 3 jours/3 nuits sous averses régulières et orages violents,étanchéité parfaite ! Ayant testé auparavant d'autres imperméabilisants,je recommande vivement ce produit + performant (Fabsil Gold est recommandé par les fabricants de toile haut de gamme anglais...).Rapport qualité/quantité/prix excellent.
