That would be great as long as the sealer would stick to it. I am looking into it more. The sealer I have claims it will stick to almost anything. Including glossy sufraces. Lists quite a few things like aluminum, steel, wood, ceramics. And goes under and over oil and waterbased paints. Maybe I'll try to superglue a large spot on a scrap piece of wood and see how well this stuff will stick. Let me know if you paint soon what you get.
