Coming back to the hobby after a long break. Altohugh i have an airbrush i am going to brush paint the models to start with. Read helpful suggestions about how to paint and a rough ration of 7 parts paint to 1 part water for acrylics. Not sure just yet if i will be using Humbrol or Revell acrylics. Is there anything i should know about each paint that might help me choose?
