"Keeps the rain out of my TVR"

I have been using this to waterproof the roof of my TVR convertible for years. It does the job well and only needs re-application around every 18months. Recently Fabsil Gold has come out too but I am sticking with the standard product as it also contains a UV protection that should help prevent the colour of the roof fabric from fading. Brilliant product, thanks!
