My 2015 Kia Forte 5 had problem with paint oxidizing on the rear spoiler about hatch. It started after about 4 years and just kept getting worse. It was pretty bad and very disappointing for what I considered a pretty new car. I have seen the same problem on some Elantras of same vintage. I suspect it is related to the fact that the spoiler is plastic. I approached KIA for help but they said it was beyond warranty.
I tired a few products I had around the garage to fix it. Waxes, compound and scratch removers. Some of the efforts made the spoiler look great but the results only lasted a few days and signs of oxidation would come back.
So few weeks ago I bought some Meguair's Ultimate Compound. I applied and worked it by hand using an application sponge and some cloths. I did not have a machine to do it. As the problem was just on the plastic spoiler it was very doable.
It took a little elbow grease but I am really happy with the results. The oxidation is gone. I waited a while before posting results just in case the oxidation would re-appear. It has been at least 3 weeks and it is still perfect.
Really happy with this product and the results. I would recommend it.
