Hi all.
Thinking of using wfp (for first time) on some houses.
However, have experienced some upvc windows where - if you touch the black glazing seal with your cloth/scrim (whilst detailing) an ugly black streak is dragged onto the white upvc frame. And its a bu**er to get rid of.
What happens with wfp when the brush bristles touch the seal?
Thanks. Will read later - 6 ton of hardcore just arrived for the garden!.
