Dont reem me out. I use to be a small time painter doing everything by brush or roller and have recently teamed up with a larger company. I am wondering peoples opinions on spraying exterior siding (clapboards and shingles) and backbrushing. Obviously it is better to backbrush but how much of a difference does it make in terms of durability. I am in a competative market and there are other companies that spray siding and dont backbrush. If the prep work is solid what do I sacrifice if I dont backbrush? I know there is no difinitive answer but any thoughts will help.
