Coming back to the hobby after 40 years, So some advice would be appreciated, I am reluctant to use a spray gun because of dust and difficulty in ventilation, is it possible to get a good finish with flat brushes ?? and if so are the airfix flat brushes good enough or any recommendations?, I was looking to use acrylic paints again because I believe they have less fumes ?? again are the airfix acrylics or other manufacturers better ?, I read but can't remember where that there is a chemical that aids acrylic paint to give a smoother finish when brush painting ?, is it practical to use an airbrush in a garden with just a cardboard box as a shield ?? and I think that my first model will be a tank in 1/76 scale if brush painting acrylics can i use weathering effects ?? oils etc etc on the acrylic or does it need to be sealed first, for brush painting will i get as good a finish with acrylics or enamel ?? probably should have asked that first. I appreciate all answers and help Thank You
