Hey Guys,
I always thought this patch of bubbles right below the door jamb on my Bee was rust. I showed it to body guy yesterday. He thinks it might not be rust, but instead it is (brass?) seams that are bubbling up... (I didn't quite understand what this meant..).

Anyway, he said this would be a little better news than if it was rust -- which would require a metal patch. It sounded like this one could just be ground down?

Have you guys ever experienced bubbles right here and how did you end up dealing with it?

Thanks!
