you need to know your gun and be able to tear it apart and put it back together.

know the controls, air,fluid,patteren

overlap atleast 50%

even strokes

feather on the outsides

start 50% over or below panel where you start
atomize

be able to adjust if it splatters big drop or little

know what dry spray, and overspray is

never paint over twice,wait for it to flash then put another coat on before kicks,then you have to wait till it drys completely. if not it want burn in.

dont be afraid to wet the panel, if so it may cause dry spray

be patient, take your time.
