How to Diagnose and Troubleshoot Various Ailments of the Infiniti Bumper Cover
If you 're driving along with your Infiniti and there 's a big hole on your bumper cover, then you need to stop. The only time holes in your car is acceptable is if it 's already on the scrap heap. Also, although the hole on a cover is worse than a hole in the bumper itself, it can be quite unsightly and your bumper might get damaged next on the exposed area of your cover. You should consider your options for repair and replacement when dealing with cover damage. You probably won 't replace your cover if it only has a few reparable scratches and it 'd be a waste of money to repair an extensively damaged cover when replacement is the more commonsensical answer.
Scratches and nicks on the cover
As far as nicks and scratches are concerned, you should "clean the wound" then put some finishing paste or putty on it to make the scratch blend with the finish on your cover. When dealing with plastic bumper covers, keep in mind that there are four types of auto plastic they 're made of. They could be made of TPO (it gets waxy and stringy when hot, melts like butter with high-speed grinders, and sands in chucks), Thermo-Set (easy to repair, doesn 't melt against high-speed grinders, sands powdery, and is available as flexible or rigid), SMC or sheet-molded compound (looks like fiberglass with white powder), and poly propylene (not recommended for painting or repairing).
Small holes and dents on the cover
When dealing with more extensive damage on the cover that can 't be fixed quickly with a cleaning agent and finishing paste or putty, you might also need reinforcement material, flexible contouring plastic, mixing tips, adhesive material for structure repair, a mixing gun applicator, and adhesion promoter. To repair the cover, you need to clean it out, cut off any bits that are sticking out that 's breaking the natural contour of your bumper with a razor blade, sand off any burrs with 80-100-grit sandpaper, clean the back of the cover, scuff it with sandpaper, reinforce the holes, then put in the filler. Finally, put in some paint to get it back to its original look and finish.
Extensive structural damage reaching the bumper itself
It 's around this point that you should seriously consider buying a replacement cover (although if your cover is made of poly propylene plastic, you have no choice but to get a replacement from the start since it 's not recommended for repairing). A collision as low as 15 mile per hour is more than enough to tear a gash on your bumper cover, resulting in unsightly damage. You can do the same repair steps outlined above for small holes and dents, but it will be more expensive and labor-intensive for you to do, plus if your bumper itself is damaged the cost will skyrocket compared to simply replacing everything.
Consider auto body services
If you want a lasting repair, then you should look into availing of auto body services and the assistance of professional repairmen. This remains a viable option as long as it 's cheaper than simply replacing your bumper cover and/or your bumper itself. However, auto detailing remains one of the most expensive solutions to your damaged bumper cover dilemma because it involves services like alignment, paintless dent repair, complete auto detailing, hail damage, and so forth. On the plus side, auto detailing services are much better at repair and restoration than the average DIY repair motorist, thus justifying the expensiveness of the procedure somewhat.
