So based on experience and expert knowledge, what's the best way to prep metal for lap joints, especially with plug welds? No paint or treatment? Ospho? Weld-through primer? And what about seam sealant after welding before paint?

Weld through primers I have used always contaminated the welds if they get into the welding puddle. I masked off the areas with tape where the actual welding will be then sprayed on the primer just to have some sort of protection in areas that may harbor rust in the future. Make sure the back side of the weld has no primer either for same reason.
