I was just wondering how many cans or coats do I need to put on an ash guitar that has a swirl paint job on it? I ordered 2 cans of it and I have seen articles of 1 can or 2 cans to use. What steps should I use? I read the first coat is light and then the 2nd coat goes on better. I don’t want to screw it up. Do I need to sand after every coat?
