I have dabbled with flux only a little, but the trick I found for thinner materials is bump the wire speed up and move quickly across the seam. This is where the auto dark really helps, you can pause and still see the seam without lifting the hood, and restart before the seam cools too much. Also, the flux leaves a film, so if you have to restart a bead, you will need a wire brush handy. Probably the best advise I can give, is the same as paint and body, prep time should be double the weld time. Beveled edges, clean metal, clamped in proper position, double and triple check, then pull trigger. Nothing worse than cutting out welds, but it does give you a chance to gauge how well you are doing.
