"Mitsubishi" radiator looses freon. The microscopic leak is detected at the radiator front side.

The through hole is rather small. Expected powder penetration may be miserable.

To avoid the powder penetration to the system spray K-20-11 at mode "4". The hole is closed in a quarter of a second. Now spray dense coating over and around at temperature mode "2" for sealing up.

The result if good with the minimal efforts.

One should be sure of the powder will not penetrate inside the pipe while spraying to the assembled system. If not sure do not spray. To reduce the penetration possibility press the pipe walls to close the hole to ten micrometers size. *AS*
