I have a black, 2018 Hyundai Elantra and I found what appears to be hard water spots on the top of the trunk lid. They are brownish around the edges and definitely etched in to the clear coat, much to my complete dismay!! :(

I read online that a 1:1 solution of white vinegar and distilled water can be used to remove them, but I wanted to check in here first and see if that is true in the experience of others before I do something that may damage my car further.
 
Best way to remove hard water spot etching.

I've posted this question before but maybe I didn't phrase it very well, so I would like to try again.

My car is a black, 2018 Hyundai Elantra SEL that has what appears to be hard water spot etching into the clear coat on top of the trunk hood. From what I have read, I can polish this down but doing so will require some degree of damage into the clear coat itself and so I am looking for advice into the best way to do this as unobtrusively as possible.

I love this car SO much, I'm so proud to drive it but I'm very new to detailing black cars and I could really use some advice, please?
 
Sorry that when you made this post no one answered you. Looks like you made it on Thursday, June 6th at 12:30am as in O'Dark Thirty. I'm pretty sure I was sleeping about then.


Your question and the answer is basic detailing 101 information. Anyone that’s read my book or this forum would be able to answer you. :dunno:

I was off work and while I was answering questions from home I missed this one. I did just answer you in your new thread for the same topic here,

Best way to remove hard water spot etching.


Sorry to say, if the water spots are as you describe, that is actual ETCHINGS IN the paint, then the ONLY way to remove them is by abrading the paint, i.e. polishing and/or compounding and polishing. And "yes" this will remove some of the clearcoat paint. There's no other way to fix this type of problem except to add more clear paint, that is re-paint the car or the affected area.

Sorry to be the bearer of bad news but that's the facts.

HARD WATER SPOTS - this is a term everyone uses to describe ALL types of water spots but that's not the reality of it.

Hard Water Spots means - DISSOVED MINERALS in the water. Here's a picture of Hard Water Spots from my article from 2011, 8 years ago as I type.

You can see the now DRIED minerals after water has evaporated. These types of water spots can be washed off, wiped off and/or removed with some form of LIQUID formulated for hard water spots.

They are brownish around the edges :(

That's out of the norm. BROWN around the edges?






and definitely etched in to the clear coat,


So here's the question I always ask and I ask it to make people THINK.

What's in the water?????????


Urethane paint is pretty tough. So what is so corrosive in our water that it is etching the paint?
(no one ever has an answer, not even me)




I read online that a 1:1 solution of white vinegar and distilled water can be used to remove them, but I wanted to check in here first and see if that is true in the experience of others before I do something that may damage my car further.


Here's my article on this topic - I wish I had a nickel for every time and expert made this type of recommendation.


Using Vinegar to remove water spots


You can try it. Remember I said Urethane paint is pretty tough? Vinegar won't dissolve your car's paint. If there are dried mineral deposits, like the crusty stuff you see in the pictures above, then vinager MIGHT break the bond between the crusty stuff and the paint and allow you to wipe them off or wash them off. You won't know until you try.

If you in fact have Crater ETCHINGS or IMPRINT RINGS - like I show in this article,

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


Then you will need to abrade the paint and level it to visually make them disappear.


Here's my recommendation...

Or hire a qualified detailer to do the work for you or learn to live with them.

I merged your two threads. Posting two threads for the same topic leads to confusion. :xyxthumbs:


When no one is answering your thread it's better to bump the thread to make it rise to the top of most recent posts or show up on the recent threads list on the forum homepage.


:bump2:
 
Hi, Mike! Thank you for replying. I'm still learning the forum etiquette, next time I will bump instead.

I read over your article about the types of water spots, it definitely looks more like the Type II on the Corvette photo you posted. Using the detailing spray doesn't affect it at all. Tomorrow is supposed to be sunny (which is always a 50/50 proposition here on the coast!), I'll get a closer look and try to take a picture.

Good question about what's in the water that can cause something like this!!

Thank you again! :)
 
I had some strange brown hard water spots last week. Luckily for me my car was coated and the hard water spots came off with not too much effort. Another good reason to use a good LSP and keep it fresh.
 
So I tried to take some pictures today of the water spot but they didn't turn out well. However, having read the above article several times, it is definitely a "crater etching", and even in the bright sunlight, it still appears to me that the edges of the crater are brownish. I've only had this car five months and I began reading up the night I brought it home on how to take care of black paint, so I'm positive this happened at the dealership, before I bought it.

In any case, it appears that I will have to go ahead and either buy or borrow a polisher and level the paint, as you said, to get rid of them. How frustrating to have a car with only 6.6K miles and already have a paint issue!!!

@rlmccarty2000, what is an LSP? I'm not familiar yet with the terminology here.

Since he doesn't even have a DA, I'm assuming he's very new into this. I'd change that last sentence to

"If there's an etching behind, you'll want to get a trusted professional to correct it."


Now that I've gotten into this at a journeyman level, I'd personally look for a professional who would be patient enough to let me observe and learn from his technique.
 
Hello again! Thank you for all the replies and information! Today I was able to take a good picture of the water spot, which is about two inches long and 1.5 inches tall. It is definitely etched into the paint, unfortunately.

To Scott In Houston, I am actually a "she" and yes, I am very new to this but completely committed to doing what I can to take care of this car. And I agree completely, if I end up needing this handled by a professional, I want to watch and see exactly what they do, it's the best way to learn!! :)

Thanks for coming back with the picture. I've downloaded it and then uploaded it into the gallery so it can be "inserted".

Here's my comment.... I share this article a lot because my guess is the average person does not realize how THIN the factory clear layer of pait is on their car.


Clearcoats are thin by Mike Phillips

The majority of cars being manufactured today and starting since the 1980's use what's called a basecoat/clearcoat paint system. With this system, a clear layer of paint is sprayed over the top of the basecoat which is also the color coat or the layer of paint that has pigment in it. If the car has a metallic finish then the metallic flakes are also in the basecoat.

The basecoat doesn't offer any gloss or shine and in fact it's dull or matte looking after it's sprayed. The basecoat gets it's gloss, shine, depth and reflectivity by the spraying of the clearcoat layer of paint over the top of it. This is why if a person removes too much clearcoat when buffing and they expose the basecoat it will appear to be a dull round or oval spot on a body panel. The part of the paint system that adds beauty has been removed revealing the dull or matte basecoat layer of paint.



Just how thin is the clear layer of paint on a factory paint job?

The factory clearcoat on a new or modern car measures approximately 2 mils thin.

The average post-it not is around 3 mils thin.

What does this mean?

This means the factory clearcoat on a new or modern car is thinner than a post-it note. The next time you have a post-it note in front of you, feel a single post-it note between your fingers. Like this...

This experience will drive home the point as to just how thin the clear layer of paint is on modern car with a factory paint job.

It should also drive home the importance of using the least aggressive pad, product and even tools to get the job done.

When I say, get the job done, the context of this usually means someone is buffing out a car to remove paint defects like swirls, scratches, water spots and oxidation to make the paint and thus the car look better.

By using the least aggressive products you "get the job done" while leaving the most paint on the car to it will last over the mechanical service life of the car.

If you're working on your own cars and you're reading this you're already ahead of the game by reading the AGO forum and probably being a member so you can ask questions and get help.

If you're working on customer's cars take a professional approach as a service to your customers.


If you're reading this and you're going to do the work yourself or hire a detailer then do some research and make sure you hire a detailer that knows this type of stuff because the factory clearcoat on your car is thin.

Here's my suggestion...

Sometimes it's easy to turn a Mole Hill into a Mountain. I know you love your black, 2018 Hyundai Elantra, but my guess is it's also your daily driver. As such, it's likely going to see MORE wear-n-tear down the road. So focusing on fixing one little area that has the potential to turn into getting the entire panel re-painted if you burn or buff through the clear layer of paint and expose the dull basecoat, instead,

KISS or Keep it Simple Simon


If you don't already own a polisher, if you want to take care of your car and do-it-yourself, then make a small investment into a tool that can do it all while not breaking the bank. Then get a bottle of BLACKFIRE One Step and a few polishing pads.

Next - machine polish the trunk lid. Focus on this water spot area. You probably won't remove it but you should be able to improve it.

Then continue buffing out the rest of the car. It will look so good after you're done it will take away the pain the water spot area causes. And the next thing that will happen is your friends, neighbors, co-workers and family will ask you,
