Hi , just a heads up using KROWN UNDERCOATING and maybe other petroleum based undercoat. I had my 2021 sx night edition undercoated in 2020, 2021,2022. Unfortunately all my bottom rubbers around the doors and the hood swelled up badly and unglued from the body . After an estimate of over 2000.00 dollars to replace , i find out that krown is definitely skating with this and blaming kia for bad rubber seals. Kia did show me that the problem existed under each drain hole , therefore a undercoating issue at best . Krown head office is trying to push this under the carpet and delaying any chance of fixing the issue. Krown should advise their franchises about the issue instead of taking our money and passing the buck. I am calling this an expensive learning experience. SAVE YOUR MONEY AND DO NOT GET YOUR KIA UNDERCOATED.
