My opinion on claying a new car. Based on this
article. And experience with my new 3.
my decision process.
Why is clay used on a car's paint finish?
To remove contaminants from the paint. Whether the paint is single stage
(color only) or clear coat finished, airborne particles (fine metal dust, acid
rain, chemicals, minerals from water marks....etc.... ) become imbedded in the
surface of the paint. Not all of the contaminants can be easily felt.
Does a new car's paint benefit from claying?
IMO: A car's paint is only new when it still sitting in the assembly factory not having it's paint exposed to the atmosphere. These cars are shipped thousands of miles from Japan. I don't think that they are wrapped in plastic bags to make the trip. They do have some protective plastic covering some of the paint. But I believe there is still paint exposed to the atmosphere. I don't know if movement by train is part of the shipping. But, the air around railroads and rail yards contains high amounts of metal dust in the air. But, really the most important part is that you car's paint is starting to be contaminated with industrial pollutants the moment it is exposed to the outside atmosphere. In Japan. During shipping. Sitting at the car dealer.
My experiences with claying my new car.
Was there any contaminant present when I started to do a full detail on my new car? Yes. Most were not easily detected. I had to use a plastic bag over my hand to magnify the feel and sound. A few spots were easily felt with my fingers.
Bottom line: There was atmospheric contamination on my new car's (less then 1,500 miles) paint.
Would I recommend clay for a new car after my experience?
Yes.
Spot claying.
If you spot clay beginning with the first detail and you maintain your car by this standard. You should
never have to clay the entire surface. IMO.
My daughters Winning Blue, 5 Door, 3 is due to arrive 1st week in May. As soon as I can get her to park it for 4 or 5 hours. ( That will be hard. I know I just wanted to keep driving and driving and driving when I got mine).
I will:
1. Wash it.
2. Spot Clay it by using a plastic bag over my fingers to find contanimation and just clay those spots.
3. Follow with a cleaning/glaze/wax
4. Ending with a finish wax.
That is what I did for my 3 and what I will do for my daughter's 3. I hope you can benefit from the information I tried to provide. The final decision on how to precede will be dependent on how close to perfect you wish your paint to stay.
Best of Luck and enjoy your 3.
