Hi Mike,
what should I use to remove the mineral etching water spots on a C7 Transparent, tinted roof panel? I have bought all sorts of glass type cleaners to try to remove the spots. Also, I have purchased ceriglass and glass polishing pads to use on my older cars windows ( which works fantastic as you know on removing water etching on glass) but I am sure it will be too harsh to use on the tinted roof panel. Some people have suggested that I use a finish polish on the C7 tinted roof panel. However, before I try this option out, I wanted your opinion as to what is the best thing that I should use to remove the etched water spots.Thanks for your suggestion as to what I should do about this problem.
 
Can anyone then give me a suggestion on how to correct this problem in this thread? I have been told in a detailing group, I joined from Autogeek, to use a finish polish on the top but which one? I have literally bought all kinds of products from Autogeek ( sent another order in on Saturday) but want to try the one product that will be mild and least likely to damage my C7 transparent top but yet has the biggest chance of working on this problem. I don't want to just start grabbing and using any finish polish I have because I am sure someone out in our detailing community has run across this problem before and knows exactly what product I need to use to correct these etched hard water spots...I hope someone can help me and give me the name of the product they have used previously on this same type of problem I am trying to correct ..

that's a tough stubborn part of the car.m101 by hand will make a improvement.that's if you have tried every spot remover.or fg 400 may improve that with out instilling micro scratches. I used m101 with a 3401 and came out 85 percent.
 
I think that top is acrylic so to much heat with a machine may scour it.To be on the safe side rub it out by hand first .So many products out there but from my experience FG 400 worked pretty good but I used a blue rupes pad with a da.Then went back over it with griots perfecting cream with a thin pro orange pad.Wasn't 100 percent but a major improvement and this top was hammere
 
Can you feel if the spot is raised or is it indented? If it is etched only polishing will help. If it is raised like where water has left a calcium spot try CarPro Spotless. If it is acrylic using a polish will likely create hazing, and if that happens the only solution I know is replacement.
 
I tried using DG Nu-Glass on Corvette roof panel once. AND ONLY ONCE.

An abrasive glass polish is way too aggressive. I had to hit the panel with M105 and orange pad like 4-5 times to get the marring out. The stuff is very tough. Start with a finishing polish and work your way up in aggressiveness until you get results.
 
I'm pretty sure the material you're working on is

Lexan

Be vary careful with Lexan plastics - they don't like to be abraded.

If the water spots are TOPICAL, that is like mineral deposits sitting on the top of the surface a liquid water spot remover "may" work.

Optimum MDR is also a very good liquid water spot remover.


IF the water spots are more like Type II Water Spots or CRATER ETCHINGS then it's game over.

Even if the water spots are like Imprint Rings - I doubt you'll be able to remove them without leaving the surface dull after compounding it.


It's hard to say without doing a bunch of CAREFUL testing but in all my life I've never seen a product that will remove defects out of Lexan and leaving it looking 100% FACTORY NEW and FACTORY CLEAR and from experience this is what everyone' EXPECTATIONS are.

So if you expectations are for 100% clarity like brand new glass all I can say is good luck. And if you find a product that removes the water spots and doesn't mar or cloud the top please let us all know about it.

This article I wrote in 2012 doesn't reference all the new LIQUID water spot removers on the market because when I wrote it they didn't exist.

The INFORMATION in it about

Hard Water Spots

And what they really are and how they are removed is still just as accurate today as the day I wrote it.

It's educational and this is important because there's a lot of bad information out in the blogosphere and the Facebook world about what water spots are and how to remove them.


Using Vinegar to remove water spots


Here's another article I wrote, this one back in 2011 about water spots.

Very good pictures and definitions.


3 - Types of Water Spots - Type I, Type II and Type III


Type I

Type II

Imprint Rings - These are kind of Type I and Type II

Sorry pictures aren't that great and products sideways ��
I have used so far on the transparent top for my 2014 Corvette Coupe: carpro Iron X LS, Optimum MDR, CarPro Eraser Intensive Oil and Polish Cleaner, Glass cleaning Clay from Griots with Stoner Invisible Glass - glass cleaner. None of these products have made a difference on the hard water etched deposits on the transparent top. I have ordered additional products to try to solve this problem and when they come in, I will use them next on this transparent top.
 
View attachment 55481View attachment 55482I found this product outside with my other detailing supplies so I tried it also on the etching spots on my transparent top. Word to the wise ..don't spray Plexus Plastic cleaner Protectant and Polish in your house, like I did. My dogs and I started coughing and choking from breathing in the fumes from the aerosol spray. This product didn't work either on the hard water mineral deposits/etchings on my transparent top either.

Well also found CarPro spotless in garage and tried it to..nothing changed 😞 Also used Driven glass cleaner and made things worse imo. Now I really will have to wait on new order of products from Autogeek to see if the new products can correct this etching problem even a little bit, as everything else I have tried thus far has failed.
 
Going to be tough to polish those
water spots out of the "hard coat"
film-layer that is on these panels.

Some people resort to sanding the
hard-coat completely off, and then
re-spraying it. Hope you don't wind
up having to go that route.
