Folks I have a large double width, up and over, metal garage door that I wish to paint. Well that's partly true. My wife wishes me to paint it. Any pointers to the best method to get a nice smooth finish. using a proper painter & decorator is not a workable solution as Mrs M is firmly of the belief that I should do this. I also need brownie points. Using a painter while she is away will also not work. My nostrils flare up when I lie so I will be found out. When recently asked if I thought the neighbours wife was attractive? My nostrils looked like Mikey Mouse's ears when I told Mrs M...No I do not. I don't want it to have the rusty "rat" look I am aiming for the nice shiney no brush strokes look that other people achieve but I never do. I am good with a brush and can use a spray gun. I have no desire to spray the entire County, so am thinking that a brush is probably the safest method for me. Not a yard broom and a tub of Dulux. Good paints to use?
