I've picked up a lot of excellent advice on this forum with regards to products blazes,vipers,BM advanced and many more. I now have 4T to add to to the list. Used it for the first time on a small bedroom on a couple of previously painted very badly plastered walls. Let it down with a little water then on with a 9" taping knife. Following day no pock marks and rubs down a dream with 150g. Feathers perfectly. And even with delivery it is still cheaper than most similar products. Thanks to whoever introduced 4t to this forum.
