yes indeed I did. That's how I found the hail damage and door dings and such. I'll fill them, and to flat again, hit it with 3 or 4 coats of high build primer, guide coat and sand again to make sure low spots are all gone, hit it with 2 coats of sealer primer, 400 sand, color, flat clear. A wee bit nervous about the flat clear...gotta practice before-hand since I won't be able to sand & buff any mistakes
