Thanks for that Alex. I still would prefer the bevel on the other side though, maybe i'll modify it.
it that a sill brush?
Yes, it is the superlite medium dual trim sill brush. I havent used it yet. I bought it based on the feedback on this forum. If i'm honest I thought there would be a lot more bristles and I cant see how they can be as good as said. I would have thought the more bristles the better but as ive only used brushes (vikan, a lot more bristles) ,with tap water for coony roofs and not yet done my first day wfp I shouldnt comment, as i know nothin! They come very well recommended.
