Need help identifying issue on PPF

[Mike Phillips]

Looks like a chemical stain from the mud and in this case, the "stain" has actually "etched" or eaten into the plastic.


Makes me wonder,


What's in the mud?


When I used to take my truck to the Foster Mud Flat Races there were hundreds of trucks and other vehicles and probably some or a lot of them would at some point be dripping,

1. Motor oil
2. Power Steering Fluid
3. Transmission Fluid
4. Gear Oil
5. Antifreeze Coolant
6. Brake Fluid

All of this could mix with the mud and/or puddles of water and end up on your paint and thus the potential to stain the paint or in your case, the PPF


I didn't get stuck often but once in a while....






Just a thought.....


Check into the warranty, doesn't sound like it can be fixed.

I run PPF on my cars and truck and use both Suntek and Expel. Suntek has a great warranty and did cover my yellowing but had to visit 'another' dealer since the original business closed.

Not sure from your photos but almost looks like finger size spots and could have been a failure caused during the installation. Sometimes the material will stretch over time and those spots will appear under the surface. Under the surface means you cannot fix it only replace it. You might try a heat gun to the spot and lightly rub them with a MF towel. If it changes anything you would be able to detect some change.

Good luck, but doubt the mud caused the spots.
