Leading the area is the best thing if you can keep from warping the panels and not have it run all over. if you know someone who knows how to lead you are ahead of the game.
I have not had one area of sealer done the way I have done it have the paint crack on the surface after 10 yrs.

Jim, just wondering,you're stating that your seam sealer is somehow stronger than lead,brazing or welding?
If someone if planning on putting their car through extremes,they would have a cage,SFCs to make the unibody more rigid, and if the welds are done right,the seams will not crack if welded,simply take the time to not only run a bead on the exterior, but reinforce them from the backside and all corners,
Leading will still crack if seams are not reinforced,brazing and leading would be a better option if welding is out of the question.
