I have noticed after watching some of the car restoration shows that they use seam sealer on welded seams after they've cleaned evrything up . My question is why use seam sealer when you can Prime and paint these areas ? Even though these are usually areas that are covered by fenders etc,the seam sealer looks really rough .Any ones help is appreciated as I'm going to be working my 57 body and removing some seam sealer to weld etc .

It serves as a sealer. Painting will protect the surface, but moisture can get into the seams causing rust. The sealer will flex yet maintain a seal of the joint. You can buy sandable sealer if you want to dress it up before painting.
It depends on the type of weld seam you have If you do a complete butt weld and grind it down, you don' tneed seam sealer. But if you do a lap weld or spot weld flanges, you need it to seal the joint. I don't see any need to put sealer on a fully welded seam. But primer won't seal a seam either.
Mom said stay out of the vault, but she is gone now so i decided to sneak in, and i am finding more great information
:tu thought i would bring this one back since i see others ask about it.
