case in point; i welded up the joints between the trunk filler panel and quarters today. this was a pretty big seam with both pieces radiused/rolling into the joint even though the flanges were tight(hard to explain but some may understand). my normal series of tacks left me with a weld that was proud in the center but just slightly recessed on the outsides since i was concerned about already putting in more heat than normal due to the amount needing filled. once finished about 50% of the weld is clean and finished, but its not as clean as i would like.
what else can be done now? what else could i have done while welding? i dont want a second pass as i know it will clean up with a skim coat of filler. would the pros be concerned at this point? do your welds always finish perfect or is good acceptable? how often can you make a repair invisible?

That's been my issue as well. In the pic I posted, I could make the weld disappear. I just don't want to thin the parent metal. Glaze will easily cover the small depression. Is this considered acceptable practice? In my mind, I would prefer that to aluminum foil in areas. Any comments?
