Cannot speak for your area, we are at Bradwell -on- sea, and it works fine for us. Best price from that site, Shepherdmarine, Malcolm Johnson, first class.
excelleent stuff, slapped it on 3 yeaars ago and just have slime, albeit did trip down the canals which cleaned the bottom.
cracking stuff, i assume you will be buying from www.paint2go.co.uk at 69 squids per 5 litre, good company good product.
over here its 400 euros for 20 litres red only...but i'll be using it again.
