Yes...that most definitly causes blisters on the casting. See pics of my 1990-93 Lionel Korean made Turbine and Southern Mikado. The maroon on the Turbine tender is the worst by far. Must be some tough paint.
Also pics of same problem on a diecast model car.
When I first pulled the two Lionel Engines out from my closet (prized possesions my parents had given me) I was completely heart broken at what I found.
Going forward I check all Korean made diecast items.
Outgassing...the diecast is finished and washed in a chemical bath. If not properly heat treated these chemicals remain trapped in the porous texture of the diecast metal...slowly working out long after the shell has been painted. My Pennsy Burro Crane frame (1990) did the same thing.
This has also plagued the diecast car industry.
This is different from diecast rot...where the diecast undergoes a chemical reaction due to acids trapped in the casting and crumbles apart.

What is die-casting "outgassing" and could this be causing the boiler casting to have blisters on it ?
