I need to refinish a classic Art Deco bar in a restaurant that I bought. It's about 20 feet long . I have refinished many pieces of furniture and used Pratt and lambert # 38. However I'm not sure this would be good for a bar. I need suggestions on what to use. And I don't have a sprayer But I would consider buying one if that would make it easier. Although I'd have to cover everything around it. I need any suggestions you May have
