best way to paint Walthers 1300 series wood caboose: Spraying or brush

Can any one tell me what the best way to paint one of Walthers’ undecorated ATSF 1300 series gold line cabooses? with the windows already attached i was thinking of using magic mask to cover the windows. i thought with it being similated wood that the sides might best be painted with a brush. and roof and ends done with a spray can. not a fan of using a air brush and related equipment that goes with it.
