Wood wash

Please can anyone help me. We used Dulux woodwash, white ash colour, on some doors about 4 years ago. They really need going over again but now I cant seem to buy it in homebase or B and Q. I have looked online but its no help as I get confused by it all. Has anyone seen any or know any online shop that could help. mooglet (Sat 16:49 04/Jul/09)
