Here is some current info that I picked up in one of my trade journals.....

thought I would share this great knowledge if you havent seen it yet.....


The return of harder clears!


So now, many manufacturers have gone back to a harder version of clear coat to gain more scratch resistance. The term of these new generation of clears is simply called "scratch resistant clears" One common name for them is a brand called Cerami-Clear which simply uses nanno, or very tiny particles of ceramic that migrate to the very top portion of the clear coat and give it more scratch resistance against car washing and normal everyday abrasions. It's a better version of the old Melamine clear coats which are also very hard. But...some of these hard clear coats are very hard and very difficult to remove imperfections. You will need to be fairly aggressive to get anywhere with some of these newer, harder clears. I have also seen scratch resistant clears that once you buff through the very thin nanno section of ceramic particles that are at the very top of the clear, it turns into a softer clear underneath and can still swirl and mar very badly, even though technically it's a scratch resistant clear. So this can be very confusing and demoralizing for a the detailer as well.

In addition, not all vehicles are using these newer, harder clears. Some car manufacturers are using the scratch resistant clears on ALL their vehicles such as Mercedes. Some manufacturers are using these clears on some of their cars but not all of them. For example, BMW uses scratch resistant clear coat on all vehicles made in Germany. However, on their vehicles made in the US such as the Z4, X3 and X5, they are still using the softer powder clear coats at the plant in South Carolina. And a couple of years ago, before all the German made BMW's made the change to scratch resistant clear, some plants would still use a soft clear while some plants had already switched to a harder version. So it was not inconceivable to see the same year and same model vehicle, in the same color with one having a soft clear and one having a hard clear. That will make buffing rather interesting, wont it?

Some other car lines are still exclusively using soft clears. So, it's not so easy being a detailer these days as you can see. There are many different types of clear coats still in use with almost all of them having their own buffing characteristics


So you can understand how even for the professonals out there, paint technology is always changing.

Thanks for looking!

 

Thanks for the info, Nano technology also can be used as far as I am concerned . Scratch proof is really a must namely if you have a metallic paint on your ride .
