The missus bought some paint from SW. It is proclassic smooth enamel finish acrylic latex. They told her to paint the MDF doors with a purdy brush one stroke and it will be good. Not so. I tried rolling them and it is not working either. I do spray paint at work and we are thinking of buying an airless sprayer since we do not have a compressor at home. Should I take them to work and do it after hours? It is HOT here in Texas. Opinions please.
