hi , Matthew of clear vision came up with a simple but effective idea,
on our wfp brushes , some of us prefer pencil or fan spray, well now we can have the best of both worlds, i made mine and its great, at the turn of 2 numptys you can change the spray pattern, just buy 2 pairs of 2 way Hagen valves, remove from plastic casing as its not needed, take it from me it works brilliantly, thanks Matthew for a great but simple idea
WORD OF WARNING when you go to buy them, make sure they are the opposite to one another, left and right, you may have to search through there racks as they look the same, but they are there,
