I've nearly completed my first build, a Tamiya M48A3, but I'm having some issues with the paint. Since I don't have an airbrush I was going to use Tamiya's Black and Olive Drab lacquer spray paints to get a pre-shade and base coat. However, is there anything important I need to know about using these cans? I read the guide on Tamiya's website, but since all you model-makers have much more experience hopefully you have some tips. Thanks in advance!
