Cavity Wax Procedure:

WARNING
Do not eat, drink or smoke while using this product. Keep away from heat, sparks,
open flames, hot surfaces and other ignition sources. Avoid breathing mist, vapors,
spray. Wash thoroughly after handling. Wear protective gloves, protective clothing,
eye protection, face protection.
Use with adequate ventilation. Respiratory: Level of exposure needs to be determined.
If required, use a particulate filter, a NIOSH-approved air purifying respirator with
organic vapor cartridge or a supplied air respirator. Filters should be replaced when
breathing becomes labored. Cartridges should be replaced when odors pass through.
Refer to MSD sheet (Links: Cavity Wax, Undercoating) for additional information and
important warnings. All warnings provided by the MSD sheet are hereby incorporated
by reference.

 NOTICE
To prevent excessive vaporization of the cavity wax, use an inline air pressure
regulator and adjust the pressure to the wax gun to 70-90 PSI max. (Labels on older
cavity wax bottles may still call for 90-120 PSI; disregard and adjust pressure to 70-90
PSI max).

 NOTICE


This procedure should ONLY be performed in temperatures above 32°F (0°C).
Ensure that all surfaces are completely dry and free of moisture before applying
cavity wax or undercoating.



Using expired product may result in a poor spray pattern and/or insufficient cavity
wax application. Discard any such product (following all applicable
local/state/federal regulations). An expiration date has been added to the cavity
wax so that any expired wax can be easily identified and discarded. The
undercoating has a manufacturing date code printed on the bottom of the can.
Undercoating should be discarded two years after the manufacturing date. In case
of questions, please contact the Kia Chemical Program through
https://www.kdealer.com.

1.

Using Quick Disconnect fittings suitable for the dealer’s air supply system, install the inline pressure regulator to a conveniently located wall air outlet and adjust the pressure to
70-90 PSI. Connect the air hose to the regulator, and connect the other end of the hose to
the Kia Injection Gun (06700 10100), used to apply the cavity wax.

2.

The injection gun nozzle should be
inserted into the service holes in the sub
frame and rotated so that there is even
coating inside.

 NOTICE
Avoid removing the nozzle from
service holes during application
to prevent cavity wax from
contaminating
surrounding
areas.

 NOTICE
Ensure all interior surfaces of
the sub frame are coated
completely during application.
2.

Perform a front alignment by referring to
“Front
Suspension
System
→
Suspension Alignment” as indicated in
step 14 of the sub frame replacement
procedure on KGIS.
