ROOF COVER

8. Replace pad by cementing pad to roof panel
with nitrile vinyl trim adhesive.
INSTALLATION
1. Check all cementing surfaces on body to insure
a smooth surface. Cementing surface must be
smooth to prevent "highlighting" of excess
cement through fabric cover after new cover
has been installed. Clean off old cement as
required.
NOTE:
A xylol solvent such as 3M Adhesive
Cleaner or equivalent should be used to r e -
move or smooth out excess old cement. Apply
solvent and allow to soak before
rubbing.
CAUTION:
Be certain to follow manufactur-
e r ' s directions when using cleaner.
2. On style equipped with roof panel moldings,
completely mask off area of roof panel which
is not covered by fabric cover. Extend tape
over windshield upper reveal molding so sol-
vent will not contact paint or adhesive caulking
material. On all other styles, mask portion of
windshield and back window opening where
adhesive caulk material will be later applied.
In addition, all doors and flat painted surfaces
(hood, rear compartment lid, etc.) should be
masked.
3. Where possible, install new cover at room
temperature (approximately 72°), to permit
easier fitting and removing of wrinkles from
new cover assembly.
NOTE:
Where new cover is installed at tem-
peratures below 72°, fabricated pliers as shown
in Figure 12-1 will aid in removing wrinkles.
4. Determine center line of roof panel by marking
center points on windshield and back window
opening with tape or equivalent.
5. Lay cover on roof panel and fold cover length-
wise, precisely at center location. Mark center
location at front and rear of cover.
6. Remove cover from roof panel and lay cover
with lining side upward on a clean flat area.
7. a. On styles where pad is not present, apply an
even application of nitrile non-staining vinyl
trim adhesive (such as 3M Vinyl Trim Ad-
hesive or Permalastic Vinyl Trim Adhesive
or equivalent) over entire lining side of
fabric cover.
NOTE:
Neoprene
non-staining
weather-
strip adhesive may be used if the above is
not available.
b. On styles equipped with pad, apply nitrile
type trim adhesive to that part of lining side
of cover that will contact the metal portion
of the roof panel. Cement should be applied
so it will overlap the pad approximately 1".
NOTE:
It is recommended that the nitrile
trim adhesive be applied with a spray gun.
As an alternate method, a brush or roller
may be used. If spraying method is utilized,
a
spray gun with a pressure cup and
specific
Fluid Tip and air cap
should
be
used as shown on chart below (or
equivalent).

8.
The recommended air pressures are as
follows:
A. Air Line Pressure - 50 Lbs.
B. Cup Pressure - 2 to 4 Lbs.
Permalastic or 3M Vinyl Trim Adhesive
purchased in the field is of spraying con-
sistency.
If
rolling method is used, a
mohair type roller should be utilized. Make
certain cement is applied evenly and there
are
no highlights
from excess
cement
build-up.
Allow cement on fabric roof cover to thorough-
ly dry.
9. Lay cover on roof panel and align to c o r r e -
spond with center line of roof panel. Determine
proper material overhang to windshield and
back window openings (approximately 2" over-
hang at seam area at back window and wind-
shield opening).
10. a. On styles not equipped with pad, fold one
half of cover back at center line and apply
nitrile type vinyl trim adhesive to exposed
half of roof panel (Do not include drip
molding or roof extension area). Starting
in center at centerline and working toward
drip molding, cement cover to area while
cement is wet. As cover is being "un-
folded'' and cemented, it should be thor-
oughly "slicked" down to avoid wrinkles
or air bubbles.
