This will assure all silicones are removed which will provide a quality repair. Step 2: Grind Tab Where the tab broke, use a 50 grit roloc disc to grind the repair area to a point. This will provide the correct shape to maximize adhesion. When grinding plastic, use a slow RPM. Step 3: Sand Tab Using 80 grit by hand or 80 grit on a dual action sander, sand the repair area to assure all areas the adhesive will come in contact with is sanded. Do not apply adhesive on an un-sanded surface. Step 4: Drill Holes Drill holes on repair location using a 1/8 inch drill bit. This will allow the adhesive to flow from one side of the repair to the other side providing a rivet like effect. Step 5: Clean Repair Area Using compressed air, blow the repair area clean. Do not use any type of solvent cleaner, as this can absorb into the plastic, which will cause problems. Step 6: Adhesion Promoter Spray a light coat of adhesion promoter to the repair area. This is important so the adhesive adheres to the repair. Allow the adhesion promoter to dry for 5 to 10 minutes. Step 7: Cut Plastic and Apply Adhesive Cut a piece of plastic from the package the tab repair adhesive came in to shape the adhesive. Support the bottom of the plastic using a spreader. Apply adhesive to the plastic, then lightly press the adhesive to the backside of the repair. Next, wrap the plastic around the tab location. Make sure the plastic extends past the original length of the plastic tab. Lastly, lightly apply pressure using a spreader on the top of the adhesive to shape the tab. Do not apply too much pressure, as this will build a tab that is too thin. Allow to set-up 30 seconds to one minute. The release pressure on spreaders and allow to finish drying. Step 8: Precut Tab After a minute or two, before completely drying, precut the tab a little larger than the tab size. Then allow to finish drying about 5 minutes. Step 9: Sand Tab Once the tab is fully hardened (about 5 minutes) remove plastic from around the tab and shape the tab using the 50 grit roloc disc, followed by 80 grit by hand or on a dual action sander. Step 10: Drill Hole The last step is to drill the hole for the clip or bolt to go through to attach it to the vehicle. You normally will not see the tabs once secured to the vehicle. However, you may choose to repaint the tab before attaching to the vehicle. You only have about 30 seconds work time with this tab repair adhesive.

For the original story, go to We've all been there --hastily putting the car in reverse, failing to check the blind spot, and cringing at the crunch of bumper meeting barricade. The resulting dents used to mean a quick trip to the auto parts store for some cheap body filler and a can of spray paint, but plastic bumper parts require an entirely different arsenal of products. Instead of the old sheetmetal bumper exteriors, modern cars hide the metal bumper under a plastic fascia in hopes that minor abrasions might pop out more easily. But if your car meets the sharp edge of a 2-foot parking barrier, the semi-flexible plastic can easily rip, bend, or break. Fortunately for your bruised bumper, plastic repair and refinishing materials are widely available and reasonably simple to use. Fixing damaged plastic bumpers involves grinding, sanding, sculpting, and painting, but it's worth the effort for repairs that would cost less than your deductible. Cracked Bumper Repair KitAfter you remove the plastic piece from your bumper (the screws connecting the plastic covering can be tricky to locate: try under the tail lights, behind the wheel wells, and below the trunk latch where we found our Honda Civic's), you'll need a warm, dry place to work in so that the repair adhesives can cure properly. But which adhesives you need will depend on the type of plastic in your bumper. Thus, the first step is to find a stamp on the inside of your bumper labeling it as PP, PPO, TPE, PUR, or TPUR. When you purchase your repair products, be sure to consult with the counterman at the auto parts store to determine which recipe is right for your bumper's plastic. Be sure to stick to the same brand for all of your products to ensure compatibility. To prep, begin by slightly scuffing the damaged area and cleaning it with plastic surface cleaner. If the bumper is cut or torn through completely, make sure to scrub the inner and outer surfaces. After rinsing and letting the surface dry, wipe the area with prep solvent, moving in only one direction. After the solvent has dried, sand the area by hand with 80-grit paper. Next, you'll need to form a 'V' groove in the damaged area on the front and back sides of the fascia. The grooves allow you to align the two edges more easily. They also provide more surface area for the repair material to adhere to. For plastic types that powder when sanded (PUR, TPUR), cut the grooves with a 24-grit disc on a sander. For plastics that smear when sanded (PP, PPO, TPE), make the grooves using a cordless drill and a rotary file. Repair tears and cuts from the back side of the fascia. If the cut or tear is large, you might have to align and then hold the edges of the repair with masking tape on the front of the fascia. Use self-stick fiberglass-repair tape to add structure to the cut or tear. Next, throroughly mix equal amounts of hardener and repair adhesive on a piece of cardboard or paper and apply it over the tape with a body-filler squeegee. When the first layer of tape is in place, apply a second layer so the threads run at a 90-degree angle to the first layer. When the repair is completed, apply two wet coats of flexible part sealer.
