I had entrusted my household painting jobs that needed attention to my 15 year old son and had been off to work. I had relented after a long fight and had expected to find the house in a mess when I returned but I was in for a surprise. My son had not only done the jobs I had asked him to do, he had done so without spilling a single drop on an unintended place. I was stunned till he disclosed the secret. A can of the Earlex Paint Sprayer was all he needed and since then I am a fan!
