Hi everyone, I am working on a large (24in x 34in ) shadow box that needs to be painted gloss black. It needs to be done cheaply so I used some MDF that I had laying around. I'm using cheapo spray paint from WalMart and am having trouble with the rounded edges not taking the paint. The flat surfaces are fine but where I used a round over bit the MDF is behaving like end grain-it's just sucking up the paint. I shot a primer coat and three top coats and still cannot get a nice finish. Before painting I also sanded to 220 grit so it should be smooth enough. Can anyone shed light on this problem? Thanks, Gene
