so I don't think it would have been exposed to acid rain. Now I have also tried white vinegar and I have even tried bug and tar remover. It still has the spots. I haven't tried any type of rubbing compound at all. Nothing at all harsh - yet.
Please understand, the spots are really most visible in the sunlight, viewing the finish at an angle. If you just view the paint straight on, you have to look to see the water spots.
The next thing, I guess, is a visit to a local body shop to see what they suggest, unless someone here comes thru for me! Maybe I'm being too anal about the whole thing! People who see my car remark about the shine...but I see not only the shine, but also the defects.
Hi: I don't have a simple answer for you concerning the water spots. I have a 95 polo green coupe with the same problem. I asked A local Corvette body man how to get rid of this and he said the only way was to wet sand. I don't want to go that far.The car looks great and I get lots of compliments. But like you said I know the spots are there if you look closely and it bugs me but I think I will just live with it. Ted
Water spots are microscopic etching of the paint caused by contaminants in the water, minerals, acids, etc. Try adding a little baking soda to the wash water or just use a good car-wash soap, not dish soap.
I had them, the dreaded spots on my last car - very noticable on black.
The first thing to try would be a good polish like Meguiar's Show Car Glaze #7 which is very mild. If that doesn't work, try 3M Swirl Mark Remover. Above that, your into the "compound" level of abrasive, a place I wouldn't go unless you had no alternative.
Both of the aforementioned products are mild enough that it will require a fair amount of elbow-grease and perhaps several applications to achieve the desired effect.
Try a quality clay bar.If that doesn't get them I would suggest to wet sand. Use 2000 grit, by hand. Follow with a good liquid rubbing compound (use an orbital buffer with a soft pad), finish it with some Zaino. (spots won't come back again)
I had the same problem. A guy from Meguiars R&D used Clear Coat Prep and a random orbital buffer/polisher. See the following link: http://www.contemporarycorvette.com/aboutus.htm
I have since bought my own Porter Cable buffer. One other tip I found to work well since I don't have the best water - don't spray rinse the car. Take off the nozzle and just let the water "sheet" rince. I have no idea why this worked for me - maybe it was a full moon.
Thanks again Claude in Montreal with Meguiars!
