What has been your experience with this? We are using SW’s best latex enamel for trim finish. My painter is not experienced with the preprimed pine, and insists on repriming everything with Binz, a shellac based white primer, before spraying the latex. He claims the latex will show all the places where primer is sanded off, joints and nailholes filled with latex spackle, and such. I think he is wasting my money.
If you are a painter, tell us what you do.
