I am appying lacquer to a hope chest and have put on 5 coats. I lightly sanded between each coat with 320 grit. Even though I have sanded between coats, each subsequent coat is not as smooth as I would like the final coat. After I put on the last coat, what should I rub it out with to get a smoother final finish. Caveat: I don't what to go as far as the padding technique and I am not concerned if it looks like a store window dining room table, I just want a smooth presentable final top coat.
