Picture of Road Film Dirt Stained Paint Ceramic Coating
Back in 2013, six years ago as I type now in the year 2019, we had a Thursday Night Detailing Class were we did the paint correction to a 1955 Chevy Panel Delivery Streetrod. While doing the Test Spot I took the below pictures to show what dirt stained paint looks like.
I know for some people, the dramatic difference in color can be surprising.
--> This is why I took the picture. <--
Until you see for yourself how paint can have a dirt film stain ON it, it can be hard to wrap your mind around the idea and what it looks like. But as the saying goes,
A picture tells a thousand words
This is what dirt stained paint looks like
The car was washed and then we did a Test Spot on the front of the fender. The front part was machine polished and this REMOVED the dirt staining. The back half of the fender is how the paint looked AFTER washing but before polishing. The point being, WASHING does NOT remove impacted dirt staining.
See it? See the difference in color and clarity?
And because I don't know what kind of device everyone that reads this article will be using moving into the future, here I've drawn a line around the area.
2 Points
1: This staining effect you see was over the ENTIRE car, not just the fender. This means the entire car was not a BRIGHT white but a grayish, cloudy white.
2: This staining effect takes place to all cars, you just don't see it on darker colors. But - it's still there.
