For people who use an airbrush, do you go back to spray cans sometimes? Is it more cost effective to buy rattlers in some cases? For example to spray larger surface areas like priming a figure a single color. I have just started out using an airbrush but find myself going back to spray cans when spraying base colors for larger figures such as leaders. I will start a new custom soon (ROTF LC Optimus) and would like a little advice in going about the base spraying for this figure. Thank you for reading and any advice is appreciated.
