ive a gardeners superlite , white one. ive noticed im getting spotting on top of glass frame, sometimes happens, ive noticed you get more splashback from this brush, what do you recommend for windows and sills. I need an all in one. mainly for domestic house windows. ive just done mine today, noticed all the spotting. 002 tds, ill change resin for next batch. can most other brushes fit onto the gardeners poles.
