Can I use Clear shellack over a krylon type spray paint? I am clueless here. I have a dining table that I want to refinish the top. I bought it last year and soon after the finish on the surface started flaking off. I wanted to sand and paint the top black. I don't know what kind of topcoat to use. It needs to be a durable one as it is our main dining table. I was going for a more flat-satin finish. Thanks in advance for your help.
