woofgang; "Ken, there is zero point keeping paint for more than a year or two." Yes, i know that, but i couldn't possibly say how long a tin has been there. Until i open it, of course. On my last job i threw 3 tins of wood stain together (don't know how long they'd been there but i hadn't stained any wood for almost 18 months), gave it a good stir and the end result was a very nice chestnut colour. Customer was quite impressed. Not only had i saved her some money, but the colour complimented the wood in her 3 piece suite and coffee table.
