Line after PPF removal

[timevns]

Removed the PPF fm from my wife's car. There is a distinct difference in the paint that was protected by the PPF and the paint that wasn't. I'm guessing the base coat that wasn't under the PPF faded a bit and that's why it doesn't completely match. I have done a paint enhancement and that didn't help with the line but cleaned the paint up quite nicely.

I am wondering if anyone has tested and verified the validity of ceramic coatings reducing UV aging of paint. I'm going to PPF the front of my new F150 and ceramic coat the rest of the truck with CSL and ExoV4. I'll be using C2v3 as a topper every month or 2. Will that be enough protection to keep the paint from aging at a different rate as the pain protected by the PPF? Thanks in advance for any insight!

That color shift may be from fade as you imply, but it is far more likely to be from a chemical reaction and subsequent staining of the clear-coat by the adhesives of the PPF.

Not sure of the properties of the adhesive used for PPF but I've seen this type of staining/color shifting caused by other adhesives, i.e., decals, stripes, etc.

What's even worse, if you repainted over that without first stripping the existing finish, there's a pretty good chance that the line would telegraph through in the new paint finish.
