even with elbow grease and instructions, Turtle wax Chrome related product didn't bring any results to me.
May be, I need to use buffing machine?

I've use this to take mild surface rust off. It did take a lil work, but the end result was great. It had a few pits, but with the polish it was hard to notice them unless you were at a specific angle and knew where to look. If it worked on surface rust I'm positive it will be great for water spots.

I went to a detailing place to try to get my window trim shiny again, they tried and then just suggested I get it a vinyl

Mine was looking bad and I hit it with a clay bar and it removed the water marks and oxidation. It really restored it's luster. I think the trim is clear coated aluminum (or plastic in the case of the grill)

With all the vehicles I have owned and restored I would say either leave it alone or replace the pieces. You will not be able to make it look like new again after water spots are burnt in from the sun.

If the clay bar does not work, try a magic eraser

Thanks for the reply. Have you seen long term damage as a result of attempted spot removal?

I just tried meguiars water spot removal. it removed maybe 20% only . What polishing compound did you used?

I am curious about that clay bar. My water spots are really really set (from many months) in the window trim.

it was some turtle wax product for swirl marks. it made a nice difference. i was able to feel when the water mark was removed while working it. But it was a lot of effort. Made me think there had to be a better way.

Ok, I tried today the clay bar. It did worse than the actual water spot remover. It did absolutely nothing.

So, what else to try? I have a dual polisher, that with a polishing compound will probably be the last option.

Anyone knows the part numbers or in which section can you find this window trim pieces? I have searched but to no avail.

thanks for reporting back on the clay bar. try the polish by hand. it works but requires some elbow grease.
