Can of worms

You never know what kind of worms are in a can till you open it. I started carving on this,because there were some bubbles. It was an old repair,braised together.The repair held up well for years,but it was starting to corrode,and gassed up under the bondo. Also there was too much filler(bondo),the "cave & pave"method.I will push the metal out some before I refill it.
