Grangers Fabsil Waterproofer - 5 Litres by Grangers

You cant go wrong with this fabric waterproofer by Grangers, good stuff!

Lo puse en el carro tienda por la mañana y por la noche ya pudimos dormir, sin olores ni nada, y esa misma noche nos calló bien de agua y no caló nada de nada.

I bought this to waterproof the roof of my convertible. After trying many (often expensive) specialist products which I have always been left disappointed with when the waterproofing washes off with the power washer I did some research and Fabsil came up a few times so I thought I would give it a go. Tips. Make sure the roof is clean and fully dried out before application. Preferably clean the roof the day before. Work on a warm day. Apply in the shade but position in the sun to dry out. I used a clean paint brush to apply and worked along the roof in strips in one direction making sure to soak the fabric with Fabsil. I allowed the roof to dry in full sun for about 6 hours then applied again but in an opposing direction to the first application again making sure to soak the fabric, again leave to dry out in the full sun. Leave at least 24 hrs until the roof gets wet. The results where amazing, water beads on the roof and never soaks the fabric, I applied this 3 months ago in September and it still works just as well as when first applied even with washing the car most weekends. I would expect this to last through winter without another application. I have a S3 convertible to give an idea of roof size, I reckon I used about 1/3 of the can so great value. The product made my roof look blacker and almost sparkle in the sun. I have a new car but would imagine that it would darken a faded roof. It does smell a bit at first but the smell soon clears after a few days. BEST product I have tried to waterproof the soft top.

Easy to apply by spray or brush works very well lasts if put on correctly about two or three seasons/years. It's the one I always use.

Pretty good - bit difficult to spray on my tent but seems to have made it more waterproof.
