Waterproofing Bivvies

I have had my bivvy for years and there was the odd drip of rain coming in today. Does anyone know what the best product is to use to rewaterproof it if there is one on the market.
Thanks in advance.

Found an article in aprils maximum carp bout bivvy cleaning and reproofing, fabsil universal fabric cleaner £8.99, fabsil gold £16.99. Both from trakkerproducts.co.uk , hope this helps mate

Cheers mate. Im getting some.

if you haven't gone ahead and got it yet, try and get the paint on stuff rather than the spray stuff. It's much better coverage with the hand painted on stuff.

Doh! mines on its way in the post but will keep it in mind if i need some again. Cheers mate.
