I have never had a problem with this before. I just bought my wife a black 99 Grand prix gtp. The dealer washed it and it now has water spots. I used white vinager on it but no luck. What should I try next? Would a clay bar remove this? Thanks

 

If the white vinegar didnt get them off, then a clay bar should, I would recommend clay barring the car anyways.

Here are some tips

Most 'fresh' mineral deposits (water spotting, acid rain, etc.) can be
removed using household white vinegar full strength. This is acetic acid and will
loosen and remove the mineral deposits and not harm the paint surface. Most of the
time,
the water spot etching you see is simply the hardened mineral deposit, giving the
illusion of etching into the paint. Believe me, when these mineral deposits harden.
They become really tough and hard to remove. The trick is to not give them a
chance to harden.
If the above fails, then use a Clay Bar to remove them....
If those water spots on your car have been there for a while. They might
be already etched into the clear coat. If Clay Bar will not remove them. Then what
you are seeing is an etched spot in the paint surface, similar to acid rain mark
etching..

Although, I am totally against using an abrasive product on todays clear
coated finishes. It's possible in your specific situation, you might not
have a choice. I would try 3M Foam Polishing Pad Glaze Swirl Mark Remover
part #39009 by hand, not by machine, using very light pressure. This should do
the trick. Be careful when doing this and only do the water spot areas, as the 3M is
abrasive and will remove paint material. Don't forget to reapply your favorite wax
or polish as the 3M product will remove any polish/wax.
If you opt to go with the 3M Foam Polishing Pad Glaze... see following tips...

3M Foam Polishing Pad Glaze use By hand:
Simply apply a small amount (about the size of a quarter) to a cotton
diaper or piece of cotton towel and rub back and forth into about a 1' X
1' section using light to medium pressure until it starts to dry out.
Then take a second towel and lightly rub back and forth until the polish
residue disappears and the gloss comes up. If there are still some
swirls visible you can repeat this step until they are minimal. I prefer
using a less aggressive product a couple times instead of using a more
aggressive product once. After you are done you can wash and apply your favorite
polish/wax..
