Yellowish mold or something

I have a double cab white truck and the clear film Toyota puts on the back door jam and on the front of the rear wheel fender is turning a yellowish color. I think it's mold but not sure. I've tried perozide and diluted bleach and it didn't help. Is there anything iI can do for it or should I just take off the clear film? Does it really do anything? Thanks

 

Its supposed to protect from rock chips..the "mold" is underneth the film, it looks worse then it is because the film is fading, turning yellow. Peel it off.

 

Sorry forgot to say that it's only yellow around the edge.

When I bought my truck, I had the dealer re paint my fender flares under the TSB for the flare's paint finish. Most of our trucks have a "orange peel or non matching finish from the body to the flares". Looks great now, but when it was finished, the shop manager and I agreed it would look better if we leave the plastic film off. 4 years later, only a few small nicks you would never notice unless it was your truck. Just take the plastic film off
