    My silver/grey KJ has oxidisation on all exterior plastic. I was told that, after cleaning, use a mixture of WD40 and Silicone spray and rub in thoroughly. I did this to the spare wheel carrier and it came up very well but after a week started to tarnish again and look dull. My local automotive paint shop has showed me numerous products to clean and polish plastics and my Jeep agent has told me of other products which all seem to be like cut-n-polish or different types of silicone based waxes. I've tried a few but I think the WD40/Silicone lasts better.
    Does anyone have any "secret recipes" they have found to last?

    I'd think any petroleum based products would have the
    Petroleum s evaporate and leave a chalky residue - msbe the petroleums are just for stability until application...

    I can see merit in the silicone claim though.

    If we are talking about all the black plastics, that like to turn greyish white..
    I use Mother's Back To Black.
    It works well after you use it for a while consistently.
    On my weather Tech digital fit liners, it was the only thing that got them black again.
    They were quite faded but not for long!

    This stuff from Eastwood looks like the ticket. I've used other products from them and they do exactly what they say.

    Eastwood Plastic Resurfacer

    They even use a Jeep Cherokee's flairs for their demonstration.

    I used Wipe New over a year ago. The step on the top of the rear bumper was especially grey and spotted, it took two applications.
    It made the trim look like new and 12 months later it still looks new.
    There was enough to do two KJs

    x2 on the heat gun. I did that to the black rear step and it looks almost new. I have spilled a few things on it over the years which keeps it from looking perfect.

    Well basically you heat it up until it looks almost wet but not so much that it deforms it. Makes it look brand new. I'll try to take pics when I do it to the indent in my bumper.
