I was about to suggest that he use Mapp gas. But wiki says it's been
discontinued for years. (I didn't know.. guess I should hang on to
the half bottle I've got.)
Is the propylene some inferior substitute?

Ohio based Worthington Cylinders has issued a voluntary recall of its
MAP-Pro, Propylene and MAPP cylinders due to a potential leak.

Established in 1955, Worthington Cylinders prides itself in the safety
of its products and in workplace safety. In keeping with this mission
statement, the company has issued a voluntary recall of a number of its
cylinders.

The MAP-Pro, Propylene and MAPP cylinders have been recalled. According
to Worthington Cylinders this is due to, “a potential leak occurring
when a torch or hose is disconnected from the cylinder.”

The firm has not received reports of injuries or accidents related to
the issue.

cylinders for a refund, visit www.mapcylinder-recall.com


Basically it says that the seal in the valve can leak, so If you attach
a torch head just leave it on till the bottle is empty.
