Thanks for your replies.
What I might do is try both and see what the best results are.I really prefer acrylics to enamels but if I get better results from enamel paints then ill use them.
Going to use a Tamiya flat brush and spray primer the model first to get a better base coat before painting.
I would buy a new airbrush but I have nowhere to spray in my house and also have 2 young children 6 and 3 so its not an option.
Thanks Matt and Robert
