I am confused as my Jeep has not suffered from the same discolouration but it got me thinking.
Almost 5 years ago when I bought the Jeep it was recommended to have "some kind of coating" applied to preserve the paintwork. I would be telling lies if I agreed with anyone as to what that coating was.
Presently I have no discolouration anywhere on my red Jeep and red is supposed to be the worst colour for fading. Who knows if the solution was applied to the plastic. Whatever it was worked and it was only guaranteed for 3 years.
When the external plastic on occasion shows a slight lightening of colour it gets a microfibre cloth soaked with "dash board/plastic trim restorer" applied to it. To be fair it always gets the same treatemnt when I wash and dry the Jeep.
Therefore is it possible that by constantly applying trim restorer that I have alleviated the potential fading that Gewehr and others are experiencing. Could the issue be down to lack of maintenance to the plastic trim?
I know that can read that some people cannot be bothered to maintain the appearance of their Jeep but that is not what I am trying to convey. I am merely asking if I have a solution.
