I spray 99.5% of my residential customers, but a few would like it brushed on. Bushing for me takes longer and had more call backs for touch up spots. Bushing works for me but only on flat driveways with no low spots. Spraying for me has worked well and we have minimized the brush in some cut in areas by using boards around the curbing and other surfaces areas. I am not bagging on brushing I see allot of guy doing it and some places that's all you can do. What method do you prefer and why?
