Grangers Waterproof Fabsil GOLD Silicone Concentrate, 1 lt UK,Black

Fabsil is fantastic. I bought specifically as when researching for the best waterproofing protection, fabsil was at the top of the list and my word did it live up to its name and claims.Comes with pleanty of liquid so you don't feel you have to use sparingly, very good instructions making it easy to apply and is very, very waterproof.I re waterproofed my single skin canvas roof tent. It has been used since in awful weather but held up to the elements with no issues at all.Highly recommend :)

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.

Excellent product which is easily applied with a brush and lasts. My photo shows where I missed and area of the roof and this wetted completely during rainfall, whereas the treated roof beaded the water just as it should. It has as a secondary benefit, during run off from many rainfalls, coated the windscreen so this is like having a water repellant screen. Water flies off with the wipers like never before, so much so, I'm putting a capfull of this fabsil in with the screen wash on my hard roofed car to try to replicate the benefit.

The media could not be loaded. The product looks promising, but I'm not sure how long it will last. One bottle only covered the windows and half of the small cabin cover, so I had to order another one. It's a bit pricey, so hopefully, it will protect the cover from rain for a long time.

The media could not be loaded. 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!
