I’m making a custom 10ft table for my main desk and I want to paint the stainless steal for the column and beam. I’m confused how to paint them. I like this white paint in my previous desk that I bought before. It has this noisy/grainy rought surface. Not sure if the painting that makes this noisy/grainy effect or is it a kind of metal that like this? If its the painting what kind of paint should I use?
