Anybody have a remedy to remove these suckers? there's a coat of Z5 on a little section now drying. It didn't look to improve things much. It's been in the rain a few times. There's 11 coats of Z5-2 with two Z1's(routine Z6 in there too) in the years time that the paint has been on the car.

Thanks in advance. Let me know if I need to break out the 39009.. it's standing by.

hey JD ltns..

you can try using some vinegar on the spots..it is said to work.

btw ... like the new sig and pics

Your best bet is to keep water spots while they are fresh with the Z-6.

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 have done the entire car you can Dawn wash and reapply
your favorite wax/polish or Zaino Z-1 and Z-5/Z-2.

3M Foam Polishing Pad Glaze use By orbital:

Use a 100% cotton bonnet or a foam bonnet and apply the polish in a thin lined
growing circle starting from the center and spacing the growing line about an inch
from the last round all the way to the edge. Place the bonnet flat on a panel and
activate the polisher and begin working the entire panel using light to medium
pressure. When you have worked the panel thoroughly then take a clean towel and
wipe the residue off in a back and forth motion using light pressure. Then simply
move to the next section. When the entire car is done do a Dawn wash and Zaino.

Thanks Guys.....

G... I will try that first.

KLO.... that's sure a thorough explanation! My car has two coats of clear. It's only been wet sanded to get the NIBS out..and I haven't yet used anything abrasive on it.

Wish me luck.... I'm going to load those pics I promised right now.

Nope, it's good old acid rain. I tried a little 39009 by hand.. it didn't take it out. All the more reason to wet sand and buff to make it PERFECT like it once was.

Chris@VetteFinders

I had the same problem in a few spots on a dark colored car I had. Even the 39009 was not enough to take mine out either.

J Z06

The nice thing is... there is a LOT of material on this car.. 2 coats of color/clear. So I can wet sand it out. It sucks that this happens. Acid deposits or mineral deposits like KLO said can get through anything if left on long enough.

i am sorry to hear those acid rain spots did not come out..

i got some on my black. thats what happens with daily drivers... but still...grr.. it was only there for 5 days...before the next car wash!! :mad

but one thing...i dont notice them as much anymore... i wonder if they slowly faded away with all the washings... i still see a few, but not as much as before :confused: but i guess thats a good thing :D

Good luck with your car and i guess you have to wash your car after EVERY single rain drop

Here is the order in which you use the 3M products from a sand down:
