I have a recurring problem.

I'll go through all the work to clay and correct one of my cars, then top it off with some einszett glanz. It'll be like a mirror and bead wonderfully.

Eventually, I have to take it out of the garage. Because it's Florida, the following happens:

-100 degrees and sunny all morning
-Monsoon for an hour in the early afternoon
-100 degrees and sunny the rest of the day

So, predictably, while I'm at work all those lovely beads of water just bake on on the car. They go right through the wax and substantially etch the clear. The etching is so deep you can see the difference in elevation with the naked eye. It's so bad that the only way to clean it up is to eventually break out the rotary again.

I try to mitigate this by using a car cover, and basically never driving the 911, but my Cayenne is outside 99% of the time.

Is there something that can hold up to this weather torture without me having to base my entire life around keeping the car clean enough to be covered all the time?

 

I live in Florida also. I am not an expert by any means, but I have read a lot about detailing my 991. Waxes apparently have lower melting points so it could be the wax you are using is not effective for the high heat conditions. After I prepare the surface (wash, clay, polish), I use a sealant for protection since its melting point is much higher than a wax. A wax can be added after the sealant for extra gloss especially on a dark car. Every other wash, I use a "sealant enhancer/extender" to fortify the sealant's protection. There are many products out there, but I use Adams Paint Sealant for base protection and Adams H2O Guard and Gloss as the enhancer/extender. I am using my car as a DD and the paint is excellent - no water spot issues. Hope this helps.

 

I would suggest you look into OPT Opti-Coat range (I live on a beach front in FL and feel your pain).

Nothing short of a car cover / garage will eliminate so-called water spots but these coatings definitely help decrease there negative impact on the paint surface.

One of the problems with constantly polishing paint is that there is only a finite amount of clear coat / ultra violet protection applied. A product that will remove 'water spots is OPT mineral deposit remover MDR used in place of polishing will preserve your paint thickness / UV protection (man I sound like an OPT fanboy)

 

Thanks a lot. I make sure not to polish more than every couple of years, and then just a micro polish, as to not go through my clear. I was thinking of trying the sonax nano but I've heard great things about opti-coat, other than that it is hard to install. My other issue with opti coat is that I have corrected cars that had been opti coated and, several years later, there was just no cleaning it up.

 

I highly recommend you getting your car protected with a strong coating. Modesta Glass Coating right now is the best, either BC04 , BC05 (flagship). These coating are the real deal.

HUMO

 

A lot of people swear by coatings. I don't deny that it has it place but the cost doesn't justify it to me. I rather seal the paint with a good sealer like Menzerna Power Lock and top it off with wax. I live in Florida I have never had that issue with water spots edging the paint.
Also, after each wash I use Meguaiars quick detail to dry and top it off with Meguaiars Liquid Wax.

 

MX-7 water spot remover. No matter how bad, it seems this stuff will remove the worst water spots with just a wipe down.

I just bought a Cayenne turbo that had parked on one side near a sprinkler. The dealer detail, and my subsequent detail with a clay bar and Menzerna polish failed to remove the spots, but a 5 year old bottle of MX-7 soaked into a mf cloth and the panels were perfect with no trace. Wear gloves and use in vented area tho.

 

You're getting water spots because there are minerals in the water and the water is being dried out and leaving the minerals behind.

To truly solve the issue, you need to either eliminate the minerals(deionizer will help), or dry the water yourself with a towel or forced air before it can dry naturally. When you do this, you remove the minerals before they have an opportunity to bond or etch the clear coat.

Having a coating applied will give you a wear and tear layer between the minerals and the clear coat but it will not stop water spots just by it being coated.

The solution lies within adjusting how the car is washed. Coating will certainly help protect your car moving forward though.

HUMP

 

I'm not sure how this solves his issue with pop-up rain storms.

 

If you have water spots from rain, it is likely acid rain etching. Rain water is not high in mineral content afaik and water by itself does not mark or etch. Acid rain does cause etching and is not uncommon in metropolitan areas. If you have an acid rain etching issue, wrap the car in clear bra and/or coat it. At that point, you can not control the elements, you can only try to mitigate the damage caused.

 

I've used MDR and it's been a charm to remove water spots.

-only issue I have left are water spots on the rear deck lid area of my 997.2, which have been very well etched due to driving hours in Vegas over the hot desert weather... Any suggestions on what products and techniques I may use to remove the well etched water spots in this area?

I have a DA machine but even the smallest 4" pad has not been successfull to remove the spots as the this horizontal deck lid area is too small for the machine pad to make contact...

Many thanks in advance for any help and suggestions

 

There are no minerals or "acid" in Florida pop up rain storms.
The absolute best time to wash your car is in a south florida downpour. No water spots at all after finish. I believe what the OP has is dust markings left after a rain event.
