Diy paint/high school budget

I went down to the local autobody paint shop. They surpluy a lot of shops with paint around here. I asked for a simple easy to use paint for a first timer. 1 stage, spray and look good. Well they set me up and just said measure carefully and spray on a nice day, low humidity would be best. And so I did with ease. Just the engine bay frame rails, radiator support, everything white. outside in the sun.
