SPECIAL NOTES AND ADJUSTING THE FIT
These special notes have been added so that you may complete your
installation with those finishing touches, as well as for practical
reasons. Perhaps most important is the increased level of
craftsmanship applied to your car. The extra effort will
definitely show on your car.
It is almost impossible to get an absolutely perfect fit on every
vehicle. This is due to body stress and strain, possibly from
previous body or frame repairs, resulting in the difference between
vehicles. It could also be caused by the half-dozen people
trimming the parts out of the molds, again resulting in a slight
variation in the finished trim lines. Therefore, we want to
show you an easy and precise way to make sure that your
installation fit is perfect, and help you install your ground
effects package to the highest degree of craftsmanship
possible. The steps below are only if you cannot block out
fine variations. The part must be installed on the
vehicle.
If you are a professional with experience or understand the meaning
of craftsmanship, you’ll have no problem with these simple
steps. They’re easy, and only take a few minutes.
STEP 1: Place masking tape on the body, 2 inches above and
below, or inside and outside of the problem area. The gap
between the body and the part determines the amount of bondo you
will mix up. A small gap requires a small amount of
bondo.
With Bondo spreader, press the mixed bondo down into the gap
between the part and the body covered by masking tape. Bondo
will not stick to masking tape, due to the wax on the tape.
After bondo sets up slightly (about 2 minutes), carefully trim all
the extra bondo at the top edge with a razor blade. It will
trim off very easily if you do it the right way.
STEP 2: With the part against the body, test your new leading
edges. It should be absolutely perfect! If not, repeat
Step 1.
STEP 3: You should use these suggestions on all leading edges
of panels that fit against the body. The bondo left on the
back side of the panels will be a perfect fit against the body, and
a good base for two-way tape (3-M item #2670).We suggest that you
use this black double-sided body tape on the top leading edge of
all ground effects packages. You can find this tape at any
automotive paint supply store. This tape will insulate the
panels from the body of your vehicle. If, for any reason,
your ground effects package should come loose, the tape will help
protect your vehicle’s paint, and hold it in place until it can be
reattached. This double-sided 3-M tape should only be
installed just prior to or after the final installations.
STEP 4: Remove the masking tape from the body and prepare the
parts for paint. Do this by lightly misting the part with any black
spray paint. This is called “Guy-coating”. After
guy-coating, use a sanding block with 220 wet/dry sandpaper and
water to block out the part until all the black is sanded off the
part. Next, primer the part with a good filler primer.
Re guy-coat the part and, with 320 wet/dry sandpaper, re-block the
part, being sure not to break through the primer. For a finer
finish, re-block the part with 400 to 600 grit sandpaper. At this
point, the part is ready for paint.
