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.
