  • Ceramiclear issues

    seen this on another forum and thought people here would like to know this as well. ao the conversations that took place with Shawn Kelly and with Dr. Ghodoussi was not between me and them but between the original poster and them. i am just passing the info on


    Had a phone call from Shawn Kelly at Premier Detailing about a problem he was having on a brand new Mercedes-Benz AMG with Ceramiclear finish.

    The customer bought the car brand new but brand new from the dealership it came with holograms, buffer marks and compound residue everywhere.

    Shawn is an experienced Pro Detailer and when he started having problems working on the paint he called me to discuss possible remedies. In our conversation he told me that he had heard from someone in the auto industry that the chemistry design of Ceramiclear paints is that the nano particles in the resin migrate to the top to form the scratch-resistant surface.

    I told him that I've heard of paint technologies like this but had no concrete information that this is the case for the PPG Ceramiclear. So I called the Doctor.

    I called Dr. David Ghodoussi, who has either worked for or consulted for the majority of automotive paint manufactures for more information on this subject. Dr. Ghodoussi is more than qualified to talk about paint chemistry and he confirmed that what Shawn was told is correct.

    From Dr. Ghodoussi...
    After the "cerami"clear top coat is sprayed, the nano particles of Fumed Silica (SiO2), which are synthetically engineered, migrate to the top 0.2 mils of the clear coat as it is curing.

    If you remove this potion of the clear layer of paint, the paint under it will be much softer and will not polish out or react the same way the nano particle portion did or would.
    You will at some level have compromised the the finish on the car.
    Knowing this, my opinion is that this is bad paint technology because while it might work in the testing labs, in the real world it puts detailers and car owners at risk.

    Dr. Ghodoussi said this is an example of over-engineering.

    I agree. The paint systems on new cars should not be rocket science for detailers or even car owners to work on. Daily drivers see wear-n-tear and the way wear-n-tear, (swirls, scratches, water spots and oxidation), is addressed is to abrade the surface using some type of compounding and/or polishing process.

    Paint manufactures and Car manufactures, (the companies using the paint), should know the paint on the finished product is going to become scratched and swirled and then compounded and polished and they should be taking this into consideration and providing a finish on new cars with this mind.

    To Paint Manufacturers and Car Manufacturers
    Just to note... if there are any representatives from paint manufacturers or car manufacturers reading this, cars are often times polished more than ONCE over their service life. So start putting more paint on your cars and make sure the paint can be compounded and polished by both pro detailers and enthusiast detailers without having to have a degree in chemistry.


    Choose wisely
    Knowing all of the above I would suggest that any time you are asked to work on a car with a Ceramiclear finish to first find out the history of the paint, that is... has it been cut with a compound by someone else that has worked on the car previously. If you find out others have compounded the Ceramiclear paint then choose wisely whether or not you put yourself at risk doing any type of compounding or polishing work to the paint.

    Regardless of whether or not the car has ever been compounded or polished, follow this advice,

    Re: Ceramiclear issues

    While we certainly can't argue with any of your logic here, the truth of the matter is that in real world use the vast majority of cars will never see a detailer, will never get wet sanded, will never get a proper professional detail process done on them. Here in SoCal (AKA Car Guy Heaven) the number of extreme high end cars with badly swirled paint jobs is beyond huge. Sightings of Porsche Turbos and Panameras, Ferraris (from Enzos to F430s to million dollar classics), Maseratis, Lamborghinis, Rolls Royces, even Maybachs and McLarens, Cobras, Lotus Esprit Turbos, and countless hot rods, Muscle Cars, customs, etc is, quite literally, a daily occurrence. Rush hour here is like a slow moving car show some days - my first ever sightings of cars like the Porsche Panamera, Aston Martin Rapide, Fisker Karma, Lamborghini Aventador and even a Reventon (only 20 ever made), Ferrari 612 Scaglietti and 599 GTB, McLaren MP4-12C and many others were literally while driving to or from work! In fact, this morning I was actually between a Porsche Turbo and a Panamera 4S, both black, and both in need of some serious buffing to remove swirls.

    Car makers are working with paint manufacturers to create paint systems that will serve the needs of the majority of owners in the majority of situations. High end detailing is, unfortunately, lamentably, in the serious minority. More's the pity, too, because there are so many gorgeous cars running around SoCal that really could use some talented TLC. But the owners just don't know any better.

      i agree with you that most cars no matter how much money it takes to buy them will never see a true dretailer. but this was put up more to kind of warn the detailers that are doing these vehices with the ceramiclear that they may run into issues and have a game plan before it happens

        Fully understood. It would be interesting to hear if Mercedes is now stating that removal of 0.2 mils of clear is the point where they now recommend repainting the car. Most manufactures state that 0.5 mils is the limit and we understand that Ford has dropped that to 0.3 mil as the max removal point. But clears are getting thinner these days, so that limit has to be getting thinner as well. And if the SiO2 is migrating to the uppermost 0.2 mils, that would sure seem to be the new limit on Mercedes paint.

          I doubt the manufacturer would say just because you've removed .2 of surface that it would require a refinish. It doens't threaten/compromise the life span of the finish. In the case of MB, it just means that the Ceramic chracteristics could be minimized.

            Re: Ceramiclear issues

            shocking information!, can i find out how will this effect me, as i have a nano clearcoat, and fairly regularly compound it with say UC, also i have no paint thickness gauge, so what can i do when i am in need to compound, if this 0.2 limit is anything togo by?
            also would you know how accurate this finding?

              Actually, we're more concerned with why you have to fairly regularly compound with UC in the first place. If you're getting a lot of swirls that need to be aggressively removed, what's your washing and drying process? Take care of that process so that you aren't creating swirls in the first place and you won't have to compound often at all.

                Re: Ceramiclear issues

                yeh sorry about phrasing, wat i meant was, when i need to compound i do so with UC, as it is strong enough for this paint.

                most definatley i take a lot of careful wasing, two bucket method etc, so thats not really an issue, but what i am trying to say that general wear and tear alls for a compounding at least once a year, even bearing this in mind a time could come when 0.2 limit is exceeded, also i have no paint gauge?

                also another question, although it may be a bit off topic, is that of the theory 'use least aggresive products possible', but i am struggling to understand how this would apply to nano clearcoats as they are very hard paints to correct, i have found UC the most suitable consumer meguiars product to withstand correction, so this only leaves me with one choice?

                finally i remember you replying to a question previously stating use of UC removes very minor amounts of clearcoat?, this link http://www.meguiarsonline.com/forums...g-the-CC/page2

                thanks

                  OK, thanks for clarifying that!


                  So here's the deal: if you only have very minor swirl marks then, as always, it makes sense to use the least aggressive method to get the job done. We italicized and then bolded that, because the least aggressive method to get the job done can very from car to car. For example, we know of a particular 2011 Toyota Prius that has incredibly delicate paint, and light swirls are easily removed with very mild products like ColorX, M06 Professional Cleaner Wax, or M66. But those same products, on similarly light swirls on very hard paint just won't get the job done. Even if all that's needed to remove the swirls is to round off the corners of them (thereby preventing them from bouncing light directly back at you as a prism would), one paint is more resistant to the process than another paint might be. So the least aggressive method is, technically, the same no matter what paint you're working on, but the to get the job done can change dramatically.

                  Bottom line: if the paint is very hard and resistant to correction, you simply need a more aggressive product to do the job. Because of that hardness/resistance, you still aren't taking off any more paint than a very light duty product would on very soft paint.

                  If you saw the recent thread posted about the stupid hard paint on the black 3 Series BMW, then you know "the least aggressive method to get the job done" on that car was a rotary buffer, M105 and a foam cutting pad at 1800 rpm. Everything below that level of aggressiveness was a total failure, including the DAMF System!

                    Re: Ceramiclear issues

                    thats cleared confusion thanks

                    read that article crazy or what!, thankfully shouldn't have to come accross anything like that!, so basically UC is fine for nano clearcoats?, as you mentioned varies from paint to paint.

                    also can you please shed some light on my question regarding actual .2 limit?

                    thanks

                        i have a 1998 corvette c5 which type of clear coat is that ???
                        and by the way removing swirls is a bit harder than other cars
