I fancy buying one of these as Machine Mrt do a nice little on for £30. I\nhave never used one, having always just used cans. Has anyone on here tried\none? I'm fed up with always getting the "orange peel" effect. I've had\nsome really successful spray jobs with cans, but if you look closely....\n\nThey also always warn about not being suitable for cellulose paint. Why is\nthis?
