Request: Advice on removing road acquired spots off of ceramic/PPF

[Eldorado2k]

I tried heat too, nothing.

What do you mean you tried heat?
If they’re not visible to the naked eye, I wouldn’t worry about it.

I thought the PPF was damaged so i suggested heat i didn't know you could only see the spots with a ultraviolet light


I thought UV as in the sun etc

It's probably the slip solution they used when putting on the PPF forget about it it's fine

Whatever it was etched/stained your coating. As you found out, whatever would have chemically removed it would remove the coating.

As Guz said Would polish and recoat.

Only visable under UV light.....Maybe 2 ppl were doing some procreating against your car and made a mess?

I'm pretty sure it's not the slip solution because after the PPF and coating, I went through the car with UV and they were not there. Also, they originated from the surface--visible to the eye. After cleaning what looked like bird dropping or some sort of fallout, I used UV to see if the cleaning had any effect on the coating. That was when I discovered them.

My concern is that if they were able to etch into the coating, I want to prevent them from further etching down into the PPF.

What would be the advantage of polish versus chemical removal, since they both remove coating? To me, chemical can be more surgical in that it only removes the coating and contaminant. Polishing may take more off the the surface?

Or some weirdo on his own...

Anyway... I just want to prevent any deeper etching.

Curiously, why is everyone suggesting the mechanical removal method (i.e., polishing) rather than the chemical method (Goof Off) when both work?

I VOTE FOR IT'S UNDERNEATH. If it really bugs you make a pin hole and see if it will push out. Seal back up with what the mfr. recommends.

Sorry, I don't follow. I can wipe it right off with Goof Off. It does take a part of the ceramic coating with it, but the mark goes away completely. If you mean air or water underneath the PPF, it is not, as I am quite familiar with what they look like.

As I have written above, after the coating was fully cured over dried PPF, I went through the car with UV and they were not there. Also, they originated on the surface, visible to the eye, after the car had been sitting outside. They looked like a form of bird dropping. Lastly, air or water do not react under UV like biological material does.

I’d be more afraid of what the Goof Off can do to the ppf

Honestly mate take it back to the PPF installer and ask the above questions
Othe than that i think your mind is made up on what you want to do.

And be thankful that people took the time to try and help you.
