I tried to get a refund/credit note in-store (B&Q) and the manager took the paint away mixed it and painted some on paper, hotair-dried it, and said "there is nothing wrong with the product, you may not have stirred it or prep'd the suface properly". Point blank refused - so I was not best pleased, obviously when it come to paint, the 'customer does not know best'. Have managed to get some regular solvent based 'Leyland' eggshell, so will try this. I think this solvent based product is being EU-ified, and maybe the 'quickdry' Eggshell paint ,which is supposed to be 'self-undercoating' does work with special care, but it ain't Eggshell...
