Arguments for undercoating:
* Rust prevention: This is the primary reason people get undercoating. It creates a barrier between the car's undercarriage and road salt, moisture, and other corrosive elements. This is especially important in areas with harsh winters and frequent road salting.
* Stone chip protection: Undercoating can help protect the undercarriage from damage caused by rocks and debris kicked up from the road.
Arguments against undercoating:
* Warranty implications: Some manufacturers void parts of their warranties if aftermarket undercoating is applied. Always check your warranty before getting it done.
* Trapping moisture: Some types of undercoating can actually trap moisture against the metal, accelerating rust rather than preventing it. Modern, quality undercoatings are designed to prevent this, but it's a consideration.
* Cost: Undercoating can be expensive, and the cost-benefit ratio may not be favorable in all situations. If you live in a mild climate with little road salt, the investment might not be worthwhile.
* Environmental concerns: Some older undercoating materials were environmentally unfriendly. However, modern options are generally less harmful.
* Reduced sound deadening: Some undercoatings can make the car's undercarriage a bit louder.
In short:
* If you live in a region with harsh winters and heavy road salt usage, undercoating might be a worthwhile investment. However, carefully research reputable applicators and ensure it won't void your warranty.
* If you live in a mild climate and rarely encounter road salt, undercoating is likely unnecessary. Your car's factory paint and protective measures may be sufficient.
It's always best to consult your car's owner's manual and your dealership to understand the warranty implications before getting any aftermarket treatment applied to your new car. You may also want to seek advice from trusted mechanics in your area.
