The same water we use to bathe our cars can also damage our cars' paint. The spots and damage are caused by the minerals in the water. When water evaporates off of your car's paint, it leaves behind the trace elements it contains. Calcium and metals are the most damaging elements found in your tap water, whereas rainwater may contain damaging acids from air pollutants.
Avoiding water spots is easy if you chase after them. The best solution is to use a quick detailing spray after you wash, or as soon as you discover the spots.
If the spots are allowed to dry and bake on, they will attach to and harden on your paint.If water spots are allowed to stay for more than a week or so, the minerals will etch the paint and they will have etched spots (dimples). In this case, it is necessary to use a medium cut polish (if you have a polisher) or a fine cut polishing compound (for use by hand) to restore the paint surface.
SWIRL MARKS:-
A buffer in the hands of a pro can do wonders on a car that has heavy oxidation or minor scratches. Most body shops can use a buffer to blend touch-ups to perfection. Unfortunately, many detail shops and buffer owners don't know how to use the tool, or they use the wrong buffing pads or compounds.
Swirl marks are nothing more than micro-marring in the paint surface, or more commonly know as "buffing marks". Under a microscope they appear to be a scratch; however, you cannot feel the scratch with your fingers or finger nail.
The reason swirl marks and other micro marring show up so prominently on black and other dark colors is because the sides of the marring reflect light. When you polish, the edges are rounded and reduce reflection.
This diagram shows what severe micro marring might look like in a cross section of paint.
Incorrect use of a buffer or polisher is not the only cause of swirl marks. Every time you wash or wipe down your car you create micro-marring. The severity of the micro-marring depends on your tools and the contaminants present. Here are the ten most frequent causes of micro-marring (swirl marks):
1.) Polishers/buffers with the incorrect pad or an untrained operator;
2.) Harsh polishing compounds and paint cleaners;
3.) Towels and applicators containing polyester threads;
4.) A dirty chamois or a chamois that has not been properly maintained;
5.) Wiping down a dusty or dirty car with a dry towel;
6.) A dirty car duster or a car duster used on a car with too much dirt on the surface;
7.) Not keeping your wash mitt or sponge properly rinsed;
8.) Automated car washes with brushes and other wipers;
9.) Not rinsing your car completely before washing, or not washing your car thoroughly before drying; and
10.) Using a car cover when the car or the cover is not clean.
The most noticeable area for swirl marks is the bonnet and boot. On dark-colored cars, they might also show up on the doors and fenders. Bright colors do not show swirl marks as well because they reflect more light. That doesn't mean they don't get swirl marks, they just show up more readily on dark colors. Black, of course, is the worst of all colors for displaying swirls and other imperfections.
Swirl marks can be removed by polishing. Polishing out swirl marks without a buffer is a lot of work. I recommend polishing your car one small section at a time so you can see the progress.
To remove swirl marks, use a good medium cut polish. Many polish manufacturers market a special polish for removing swirls. Swirl remover polish formulas typically contain fillers and oils to help hide swirl marks. Over time, with regular polishing, swirl marks will diminish. It's very difficult to completely remove swirl marks. Even the best towels and wash tools cause some micro-marring.
POLISHING TO REMOVE SPOTS & SWIRLS:-
If your water spots or swirl marks are severe, I recommend using Autoglym Paint Renovator. Follow the application of a fine rubbing compound with a good polish, such as Meguiars Deep Crystal Polish. Use a good foam applicator pad to apply polishes by hand. Once agai I recommend using the Meguiars foam pad applicators.
SUMMARY:-
To keep water spots to a minimum, try using a detailing spray after you wash. You can also use the detailing spray to wipe away water spots from sprinklers.
To keep swirl marks to a minimum, make sure you have good wash and dry tools. Never wipe, rub or polish in circles (straight line motions only). If you have repair work done on your car, tell the painter you want a warranty against swirl marks. This lets them know you're clued in to a quality job.
Regular polishing is the best way to remove water spots and swirl marks. Choose a good polish, good tools, and be patient.
My last piece of advice is if in doubt, ring a professional and have them do it for you. It might cost a few hundred dollars depending on the severity of the marks etc, but with the right tools such as a rotary polisher (buff) far better results will be hand rather than by hand. There are specifically made products on the market to use with rotary action polishers that achieve far better results than can ever be achieved by hand.
