COSMETIC RUST AT SIDE DOOR WINDOW BELT REVEAL MOLDING

SUBJECT: COSMETIC RUST AT SIDE DOOR WINDOW BELT REVEAL MOULDING (APPLY SOLUTION)

VEHICLES AFFECTED: 1993 "D" MODEL

APPLICATION:

----------- 1993 Cadillac Fleetwood Brougham prior to VIN #1300.

CONDITION:

--------- Cosmetic rust at end of side door window belt reveal mouldings and behind side view mirror.

CAUSE:

----- Moulding material corrodes at exposed cut ends.

CORRECTION:

---------- See Figure 1. Clean affected areas of moulding with window cleaner and then apply three coats of *Loctite Extend 754 or *3M Rust Avenger Rust Converter Kit #03179 or equivalent.

Notice: Follow label instructions for Loctite or 3M solution.

1. Clean all the affected areas thoroughly with window cleaner so they are free of dirt or rust. See Figure 1.

2. Vehicle must be at room temperature (60-80 degrees Fahrenheit; 16-27 degrees Celsius)

3. Remove attachment screw (one per moulding) located on inside of door, at rear of front door and at front of rear door (See Figure 3). This screw helps to hold the end cap in place. The end cap cannot be completely removed.

Notice: Immediately clean up any Loctite or 3M solution that may get on the vehicle interior or exterior paint.

4. Use Q-tip, small artist brush or equivalent to apply and saturate the aff- ected areas with the Loctite or 3M solution. If possible, for easier access, use a thin blade spatula or equivalent to carefully pry and hold the end cap 1 mm (1 /16") from the moulding (Figure 4) while applying the Loctite or 3M solution. If the gap is too small for the spatula, do not attempt to pry on the end cap as this would damage the end cap and moulding. Smaller gaps should be handled by applying solution with artist brush or equivalent and allowing it to seep in (Figure 2).

5. After five minutes, clean any excess Loctite or 3M solution off with a dry cloth or a cloth wetted but not saturated with window cleaner. Do not use any solvents for clean up.

Notice: Be sure that the window cleaner has completely evaporated before applying another coat of the Loctite or 3M solution.

6. After fifteen minutes, apply a second coat of solution and clean up any excess as stated above.

7. Wait fifteen minutes, apply a third coat of solution and clean up any excess as stated above.

8. Seal the ends of the moulding with a gray strip caulk such as *Kent Products Seal-N-Calk #10315 or equivalent. Remove excess sealer with towel or buff with buffing wheel.

9. Reinstall the attaching screws.

10. Do not wash vehicle or allow it to get wet for twenty four hours.
