Had my first genuine (ie, not moaning about muck on the inside when I havent touched the inside) complaint today, since using WFP.
Very loyal customer rang me up and said her windows looked terrible, and could I come and have a look? She lives in a small bungalow, but I WFP anyway, as its with a block of larger work that I already have the gear out for anyway.
Went inside and she was right! They looked TERRIBLE. Like a years worth of muck had just been thrown at the windows. Only cleaned them last night, and the problem was only really at the front of the house... so I'm guessing the problem was wind.... did them just before the gales got going last night, so the only thing I can assume is that they hadnt dried properly, and the dust that blew into the windows stuck in the water and dried bad?
Has anyone else had this problem? Or is there something more sinister going on? It isnt my TDS.... it was far too bad for that, and I've just checked it tonight and its only at 2ppm (I feel a resin change coming on).
