Welcome from wintery Australia
No such thing as stupid questions! Just remember to add info like what brush/psi/paint you are using so we can give you better answers.
What kit do you have /looking at getting ?
Are you planning on t-shirts /art/miniatures ?
Right now I have a Harder Steenbeck Ultra and a cheap Chines no name. Got an airbrush to just prime minis and then moved on to playing with painting resin 3D printed stuff and in true midlife crisis fashion I have been getting back into misspent youth of graffiti, but too old to be running on train tracks and jumping fences....would put my back out!
So, dabbling with a bunch of stuff to see what fits!
