This work truck for a roofing company had severe industrial contamination. The employee responsible for the vehicle had tried to wash it and didn’t even make a dent in it. This is perhaps the most extreme example I have come across.
The blue color is from my canopy.
It appeared that the truck was parked at a job site close enough to catch the shavings from grinding. Once those specks of metal sat overnight in in a light rain they rusted and bonded with the paint. While this is an extreme example, the same thing happens to every vehicle on some level. When a vehicle is not washed and protected regularly the contaminants that settle on the paint can and will undergo a chemical reaction and become bonded to and stain the paint.
I wish I’d had some Iron X at the time. Since it is a work truck the goal was just to remove the contamination and seal/protect it. I always keep my old clay for use on wheels or situations like this. No sense wasting a good piece of clay. I had a lot of Clay Magic blue clay, so that is what I used even though it probably was a bit mild for this purpose. I used a mix of Meguiar’s gold class shampoo and ONR as lube and probably the equivalent of 4 bars (400grams) of clay.
I usually clay a car in about 30 minutes. 30 minutes on this truck didn’t even get me through half of the hood. It took about 3 hours to clay the whole thing.
Here is a 50/50 of the progress on the hood. At the far left you can see the edge of the piece of clay and how dirty it is after less than 25% of the hood.
The same spot in the sun. Probably the worst Sun shot I’ve ever taken, but it shows the result . :inspector: Sorry, I couldn't get the fly to come back for a reference point.
