Suggested Installation

Procedures (continued)

Step 7: Remove the 3M™ Polyurethane Protective

Boot from the radome/part, turn inside out again.

The adhesive side should be facing the radome/part.

Heavily spray radome/part and boot with 3M™

Protective Tape Application Solution allowing for

easy repositioning. The more 3M Application

Solution used, the easier the application will be.

Step 9: Reapply 3M Application Solution to the

outside of the boot. Starting at the center of the

radome/part, use 1-2 inch strokes with the yellow

squeegee to smooth out the boot - removing the

trapped 3M Application Solution and air bubbles.

Step 11: Dry the surface of the boot with a clean

cloth. If the boot is installed on an aircraft, allow to

dwell one hour at 70°F (21°C) before flight.

Step 12. Small water bubbles trapped under the

Polyurethane Protective Boot may be removed by

using a small 1 cc syringe if necessary. This procedure

should be kept to an absolute minimum and should

not be used in the center, blunt frontal area of the

Polyurethane Protective Boot, is is preferable to pull

the Polyurethane Protective Boot back and reapply as

described in step 10.

Step 10: Continue using short strokes working your

way down to the base. If a bubble is trapped, carefully

peel boot back, reapply 3M Application Solution and

use yellow squeegee to re-adhere. Use a clean, lint-

free, silicone-free cloth to absorb the liquid at the

edges of the boot. This helps the edge of the boot to

stay attached to the surface of the radome/part.

Note: Small bubbles (>1/8 inch) will evaporate by

themselves in less than one week. These small bubbles

can be removed by using a small 1 cc syringe if

necessary; however, this procedure should be kept to

an absolute minimum and should not be used in the

center, blunt frontal area of the boot.

Step 8: Apply the boot to the radome/part taking care

to match the index points at the top and sides of the

boot. Reposition and reapply 3M Application Solution

as needed until proper fit is achieved. Remove index

marks.
