This is tentative solution for painting old furniture on site. I don't seek that kind of work unless they bring it to me and I have room or time but just yesterday agreed to repaint some furniture. My idea is to clean and scuff it then get the Zinnsner White Shellac primer tinted to a color and get it approved, then after that is on, add some tint or a little latex to some General Finishes HP which is harder than any other waterbased stuff I have seen (I hear Chem Aqua will work but I keep seeing technical difficulties posted on forums, so I will stick to the tried and true and trouble free for the most part GF) then clear it with more General Finishes HP, it dries very fast. I know with enough coats that this system will hold up very well, and will be fine. But maybe there is something else? I thought about a lacquer, but then the question becomes what primer to use on old stained wood. Can I maybe use an automotive primer, or can I just prime with any decent primer and use the ChemAqua, I really dont want to have to haul the furniture down the stairs and outside and the room is empty. I have to stain a few things though. I am mostly worried about the bed, I would hate for that grandaughter whose is being gifted to have her durn white bed chip because of me. I know how to spray cabacrylic and nitrocellulouse lacquers on new wood, but not sure what primer would work on old wood, that is the question, what primers.
