I have a suggestion Alpha W.

If this is your first time at "spraying" latex don't use your new plane
as a test bed .

Get a good size piece of glass and practice on that. This will help develop
your technique with thinning,pressure,and gun set-up etc. Before the paint
hardens wash it off and do it again until you feel comfortable with the process.

THEN do the plane

Good luck
