So, I ordered the PPF from Tesla and got a ceramic coating kit also. I was so excited about having a free weekend and the time to do the ceramic coating process that I completely forgot to put my PPF on beforehand. So, is it okay to put the PPF on top of the new ceramic coating? If so, should I coat those two doors again? or will it be fine without the extra coating. I just got my MY last month so not driving it for a couple days while the ceramic coating cured was awful!


I guess I am going to make this a twofer since it also deals with ceramic coating. THE DAY I drove into work after my coating a piece of metal flew up and hit my driver side door, it put a little nick in the door two places, I dont see metal but I can feel it with my fingernail. What is the proper method to fix this now? I was thinking use a little rubbing compound around the nick to smooth the edges just a little, then use some touch paint and then coat the door again? I watched a few videos on the tesla touch up kit and it seems to work well if you use a very small amount and skip the step with the leveling agent.

Thanks in advance to anyone willing to throw out some advice/expertise!

Also, for those curious, I used CarPro CQUARTZ 3.0. It took some time but was pretty easy and turned out looking amazing!

I had my front protected with PPF and the rest of the car treated with CQUARTZ. Had a similar concern as the treatment was done before I had a chance to install the rear door PPF.

Cleaned the area with IPA and had no issue installing Xpel PPF. It adheres well but tends to slip a bit long during the install.
This can be address by flushing with the IPA/water mix.

Removed one of the PPF door installs a few weeks later to re-do them (this time with the PPF wrapped around the edges) and actually had to use steam to even get the PPF to come off properly. Adheres very well.

Thanks for the input! I guess worse case it will just fall off..... Appreciate you helping out. 👍

Generally you can't put PPF over a ceramic coating as it won't adhere properly. (Though I have seen some people report that they have done it.)
I had Ceramic Pro installed in September 2020, then self-installed the rear door PPF over the ceramic treated surface in March 2021. So far install has been flawless and no sign of weakened adhesion yet but I suppose time will tell.

My Ceramic Pro installer forgot to install the rear door ppf panels and said he'd be back in 2 weeks when the ceramic was cured to install the ppf (with apologies for the oversight). He will thoroughly clean that area first though for good adhesion then put the ceramic pro on top of the ppf.

You cannot put PPF on Ceramic. It will not stick - it may for a month or two at best, but then it will just come right off while you are driving. Ceramic coating prevents the adherence of ANYTHING to the car, so if the ceramic coating was applied properly the PPF will not stick. The point of Ceramic is to make sure absolutely nothing sticks to the paint - no grime, no dirt, no dust, no adhesive, no water, nothing. You must apply the PPF before the Ceramic coating, or else you will have to do the ceramic coating all over again. Now if you did get Ceramic coating and the PPF is sticking, then, unfortunately you got scammed and that coating is not applied properly and we encourage you to find a different provider.

These are the industry standard steps we use to properly prep for PPF and Ceramic coating:

Wash
Claybar
Polish*
Paint Correction**
PPF Application
Ceramic Coating

*Note: A single layer of polish will work great on new cars and often paint correction is not required for cars fresh off the lot. After the clay bar, this will remove all defects from the paint
**Note: Paint correction is required for areas that have swirls or any other defects that the single layer polish did not remove. This is more often required in older / higher mileage vehicles. Ceramic Pro, for example, brings out any kind of imperfections on the paint so you must ensure that the surface is clean, smooth, and free of contaminants.
