probably should have sealed it and primed it. There may be some color change, and if you use hardener in the paint, some of that can seep into the filler and cause it to shrink a little.

If it looks bad after a couple more coats you may want to sand it down and primer it. No big loss.. you'll be able to match the paint back up easily
