To possibly improve the service life of deice boots and to reduce the
adhesion of ice, it is recommended that the deice boots be treated with AGE
MASTER No.1 and lCEX.
AGE MASTER No.1, used to protect the rubber aga i nst deteri ora t i on from
ozone, sunlight, weathering, oxidation and pollution, and ICEX, used to
hel p retard ice adhesion and for keeping deice boots looking new longer,
~"
are both products of and recommended by B. F. Goodrich.
The application of both AGE MASTER No.1 and ICEX should be in accord-

paint touchup almost impossible .
• Ensure that the manufacturer's warnings and cautions
are adhered to when using AGE MASTER No. and ICEX.
Small tears and abrasions in surface deice boots can be repaired tempo-
rarily without removing the boots, and the conductive coating can be

this correctly.

Most efficient cleaning is done using a spray-type cleaner. Before spray
Icleaning, ensure protection is afforded for other components which might be
adversely affected by the solvent. Refer to the Airplane Maintenance
