Hi SilverXL7,
With both of these surfaces, you want to use completely non-abrasive products and it is very important that you applicator material and removal material are clean and soft so that these two items will not instill any scratches.
I would recommend a clean, soft foam wax applicator pad.
Meguiar’s always says,
"Use the least aggressive product to get the job done"
Meguiar's Plastic Cleaner, M-1708 is a very mild polish and would be the least aggressive product to try first with a foam applicator.
PlastX is very effective at removing scratches from plastic, that said, the chrome plastic is a different animal and is going to show any marring or micro scratching very easily.
If you decide to try PlastX, you should test this product in a small, inconspicuous area first to insure that the product, and your application of the product, are not marring or micro scratching the finish.
Be very careful when working on this chrome finish. It could be that you will have to experiment with a number for different products to find one that will work, and it is possible that nothing will work. I wish I had it in front of me because I am curios as to what can and cannot be done with this type of coating/surface.
It could be that these two surfaces are very susceptible to scratching or as Meguiar's refers to it, scratch sensitive.
Mostly I want to try to stress that while the Meguiar’s PlastX is a very safe and effective product, some surfaces need to be handled with kids gloves until you have a feel for polishability, or lack there of.
If it were me, I would try the M-17 Plastic Cleaner first, and then if that didn't work, I would try the PlastX in an inconspicuous area second.
Hope this helps...
Mike
