I currently using a Gardiners medium dual trim brush and the same in the sill version. I don't have them on goosenecks but am using the extra long extension for the resi-neck. I just have the part threaded into the brush so unscrew the quick release ratchet clamp insert new brush and rethread quick release. I find this quicker than opening top clamp and removing whole resi-neck and undoing John guest fitting. Anybody do the same?
