Hazen, I doubt if the spray primers will fill the grain. It will depend upon the type of wood you are working with. If the piano is an open grain wood the filler will be a must I am using waterbase products and always first use a grain filler. Sand. Then I spray a black undercoat. A check at this point almost always show more grain that needs filling. A light thinned coat of filler is applied over the undercoat. Sand again and spray another coat of undercoat black. If the grain is filled at this point follow up with the top coats. I'm sure we have some experts on this subjects on here. I'm in the middle of a small black grand now.
