Ceramic coatings are not completely impervious to contamination.I tried out the Iron buster on my truck yesterday. While it got rid of a fair amount of the fallout, there was still some residual left behind. I did a clay bar wipe down which got rid of the balance, as well as the gritty feel on the paint. Polished up and looks like new.
My question is. If the GT has a ceramic coating on it which previous owner says it does, what steps do you take to get rid of the residual contamination if you aren’t supposed to use the clay bar on a ceramic film? I want to start on the car in the next week, but want to be sure I have what I need before I start.
The best way of describing this is to think of a ceramic coating as skin. Your skin protects what's underneath but will still absorbs and emit moisture. Just like skin, ceramic coatings actually have what are termed "pores". In the same way one would exfoliate or cleanse their skin, decontamination is needed to unclog these pores to ensure the coating performs at it's best. Decontaminating a ceramic coating will often revive a coating that otherwise appears to be failing. This can restore water beading or sheeting and improve the slickness as well.
In most cases, decontaminating a ceramic coating is focused on chemical rather than mechanical (clay) methods. There a few ways of approaching this, for best results, do all of these every 6-9 months depending on vehicle usage patterns. For a garage queen, you may only need to do this every 12 - 18 months.
1/ Wash the vehicle as normal, swapping out the pH neutral soap for a high alkaline or acid leaning soap. Which you choose will be dependent on what contamination you have. If you have a lot of water spots, then choose the acidic soap, otherwise, the alkaline soap will be fine. (Don't be concerned about the term "acid", Descale is within the limits of what the coating can withstand and is safe when used as directed.)

2/ Iron removal. Wash the car as above, after the final rinse, apply iron remover to the whole car or in sections, allow to dwell and react, then thoroughly rinse. Don't ever let these products dry on the car.
3/ The method depicted in the video below is a smart way of combining products similar to the above in an efficient, calculated way. The shift between acidic, pH neutral and alkaline seems to target contamination at all angles rather than on single hit.
1 - Apply iron remover (pH neutral) onto the dry vehicle, soak for 5 - 10 minutes.
2 -Apply Lift (alkaline) soap over the top of the iron remover, soak for 5 - 10 minutes.
3 - Rinse
4 - Contact wash with Decale (acidic).
5 - Rinse
At this point, you may also choose to apply a maintenance product to fill in those now empty "pores", helping to prolong the coating and slow down the accumulation of contaminants. You would use an Si02 type spray sealant here, think Carpro Reload, Qtechniq C2v3, Gyeon Cure ect.

So, having said all of that, I think this demonstrates why ceramic coatings are not necessarily a low maintenance choice of paint protection.
