This plastic covering is designed to deflect and deform easily when bumped. The theory goes that you can run into it lightly and the plastic will pop back into its original shape. However, really wallop it, especially with a hard or sharp object, and the plastic will abrade, cut or tear. Various carmakers use different methods of attaching these plastic bumper covers. Because they are held in place with screws and tabs that fit into slots in the body sheetmetal, you may have to do some hunting around for all the fastening points of a typical fascia. On our damaged Civic, for example, there were screws behind metal caps near the trunk latch, as well as screws under the taillights and at the wheel wells. Once they were removed, we were able to slide the bumper's tabs off a number of slots in the rear quarter panels. Look for screws or bolts under the trunk carpeting between the wheel and the rear bumper. You may also find fasteners hidden beneath or behind the bumper fascia. Grind a "V" into the back of panel to remove loose material and give more surface area for adhesion. Fascia Facelift.

Not all plastic bumpers are made from the same stuff. But with the fascia removed, it's easy to identify the type of plastic because it's stamped into the back side. Stamps of PP (polypropylene), PPO (polyphenylene oxide) and TPE (thermoplastic elastomer) indicate plastics that smear easily when ground or machine sanded. Our Civic bumper is made of polypropylene.) Stamps of PUR (polyurethane plastic rigid) and TPUR (thermoplastic polyurethane elastomer) are plastics that powder when ground or sanded. The type of filler you use to repair the bumper depends on the plastic type, and there are many different manufacturers. Consult with the counterman at the auto paint store for the appropriate products. While the specific brand you use isn't critical, it is important that you stay with that same brand throughout the entire repair to be sure the products are compatible. Regardless of plastic type, prepping the fascia is the same: 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. When wiping with this material, go in only one direction because going in two directions simply drags contaminants back into the repair. Thoroughly mix equal amounts of hardener and repair adhesive on a piece of cardboard or paper. After the solvent has dried, sand the area by hand with 8. 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, cut the grooves with a 2. For plastics that smear when sanded, make the grooves using a cordless drill and a rotary file. This gives you greater control and slower speeds to reduce the chance of heat- generated smears.
