sorry i just had to do it
is the tfr from b & Q okay to use or is there a trade rand worth getting?also how do you apply on conny roof - im guessing dip brush scrub on without water flow and then turn water on to rinse thouroughly off (otherwise any left on will set hard and be difficult to remove..yes??)how much time before its dries...especially if its a sunspot?would you then continue to use that brush head on windows (does the flowing water naturally rinse the brush head out?)....or do you use different brush head?have wondered myself as had some manky ones
