hi guys. I've been using my Gardiner backpack for about five weeks now. It was a birthday present from the mrs so to keep costs down I only asked for one brush, a supreme medium hybrid. I'm looking for a couple more brushes now. I want one specifically for first cleans and one for the undersides of gutters, fascias etc. I've watched the video on the Gardiner website and think I need a super-lite radius sill brush - single trim - flocked bristles for the gutters etc but I'm not sure about the first clean brush. Does that sound about right? Any suggestions?
