I bought a new Hyundai Elantra recently and was offered quite a few add ons toward the end by the finance guy, such as an extended warranty, tire roadhazard, gap insurance, Dupont Clear Coat, etc. I declined all of it, but I am curious about the Dupont Clear Coat. I thought that the car already had a clear coat, but if not how is it finished? Is the Dupont Clear Coat option a good thing? Would it be worth getting it done?
