the 2k i used is applied the same as acrylic, only differnece being is that it shouldnt really be done outside and you must wear a mask!.. you should wear one using other paints but with 2k its critical..

my primer and paint was $750.. and cost me $1500 to get the paint layed down, so $2250 all up..
That saying if its a backyard job acrylic/enamel is less risky and easier to use for the DIY
