NAVAJO CHIEFTAIN SERVICE MANUAL
Agemaster No. I and Icex are applied as follows:
a. There are four approved methods of applying Agemaster No. 1: brushing, swabbing, rolling and
dipping (prior to boot installation).
WARNING
Agemaster should never be sprayed as aeration will occur causing
an extreme fire hazard as well as the loss of vital compounds
needed for the protective agents to penetrate the rubber.
Container should be kept tightly closed when not in use. Apply
Agemaster only in a well ventilated area.
1. Thoroughly clean the boot surfaces of oil, grease and wax with a mild soap and water solution.
2. Rinse boots with clean water to ensure that all soap is removed.
NOTE
Ensure all soap is removed from under the leading edges.
3. To prevent staining the surfaces, adjacent to the boots, mask around each edge of the boot being
treated.
NOTE
To insure proper treatment of the boots, a minimum of two coats
of Agemaster No. I is required. A total of 0.75 fluid ounces per
square foot (200 millimeters per square meter) should be
applied. One gallon will treat approximately 150 to 170 square
feet (14 to 18 square meters).
4. Of the four application methods mentioned above swabbing is the preferred method for installed
deicer boots. If the swabbing method is selected, plastic or rubber gloves should be used to prevent the staining
of the skin. Apply Agemaster by moistening a two inch by four inch swab of lint-free cloth and tub into the
boot surface with smooth uniform strokes. The swab should be kept wet but not dripping. Cover the surface
evenly and completely. Allow the first coat to dry five to ten minutes before applying a second coat.
5. If the brush or roller method is used apply a single heavy coat at the rate of 0.4 to 0.5 fluid ounces
per square feet ( 130 to 160 millimeters per square meter) using a three inch trim roller. Cover the surface
completely and evenly and allow to dry five to ten minutes. A second coat may be applied after the first coat
has dries thoroughly.
6. If the boots are to be handled, allow to dry for at least 30 to 40 minutes before doing so. Allow
boots to dry for a minimum of 24 hours before applying Icex.
b. Icex, like Agemaster, is best applied using the swabbing method. Application of Icex should be made
whenever the boots require treatment (approximately every 150 flight hours). It is recommended that Icex be
applied only after the boots have been treated with Agemaster No. 1.
