Also, exactly how do you make the paint thinner? I assume you'd use paint thinner for that but i've only used paint thinner so far to remove paint when i've messed it up. So i don't really know what ratio of paint to thinner one would use. On another note, where would i get an airbrush and compressor for said airbrush?

i dont use paint thinner, i just put a little at a time on my brush and put it on the model as a nice and even coat, and tryto do everything in a following order, and not letting a color dry too much or it will start to pile up and give the result you currently have

and dont use paint thinner to remove paint, if you really have to remove some paint, put a little tip of a fine cloth in a bit of terpentine, i also use it to clear my brushes of paint and it works quite well, but its better if you dont have to use it, always gives a nicer result

and if you got a detailed model, use brushes which dont lose hairs, those can rly ruin your day (also use small brushes for small details, i got a very small brush otm (2-3 mm in diameter) and with about a mm or 2 of the tip dipped in the paint and then on the model gives a really nice result for those presky window reënforcements etc)

for airbrushes, i'd visit a mid to large modelling store and ask for a employee for some expert advice, you'll get really far that way and you'll prob be having a good airbrush which suits your request before you know it
