Let's be honest , most of the great techniques and materials are currently coming from Germany, and the Germans are doing it with a sponge. It took me some ages t convince my self to put the sponge on the wall , but eventually I did it. With all the different suction on site and shite multi, I am afraid lads that's the only way to have consistent finish on daily basis . I will be surprised if BG won't put it on the bag , they should, if they want to sell the crap with the black grit in it ! Let's see what response the " non monkeys" will give us then
