4. Prep surfaces for bonding by abrading and cleaning area with isopropyl alcohol. Using alignment tool, install two bushings into the canopy frame using Hysol adhesive. Clean off any excess adhesive squeeze out. Allow Hysol adhesive to cure before continuing with the latch install. A heating lamp can be used to accelerate the cure time of the Hysol adhesive. Apply 150° F for 1 hour to accelerate cure speed.
Figure 24. Prep Surfaces
CAUTION: 
Check the temperature of the carbon parts that the heating lamp is warming. Do not let the temperature get over 200° F. If the temperature gets too close to 200° F, move the heating lamp farther away from the work area.
5. After the Hysol adhesive is cured, verify that there is no excess adhesive inside the bearing surfaces. Remove excess adhesive if necessary.
