This question to answer site is so good as it shows what a so called tradesmen knows or dosent!!!!!! totally agree with comments on lowtac masking tape, dont agree with hamilton being best brushes but that is down to individual preferance, having used hamilton for many years im now coverted to purdy brushes, as i beleive they leave far better finish.I think the one thing were all forgetting is the person asking question homeowner or tradesman!!!!! if your tradesman i would suggest you give up working straight away if you need to use masking tape (gets decent tradesman a bad name) if you cant cut in you shouldnt be in game,if your a home owner you can now buy brushes already cut down like a worn decorators brush, like a fitch but much thicker, most decent paint retailers sell them
