Found 7th May 2009
Went to my local B&Q and found this cuprinol PLUS fence spray for a bargain £7.94 also had my mum and dad with me so also got a further 10% off. This is the better spray stuff with extra protection or something like that usually priced at £18.99. They had all colours available at the Stevenage store. Looks like it is in store only as could not find it online.
