I have a chemical supplier at work who supplied me with a tire dressing they developed. I planned a trip from Central Georgia to Key West, FL. The trip was a total of 1800 miles over 6 days. No rain was encountered during the trip. I put 2 coats on the tires. Here is what they looked like at 0 miles. Here is what the tire looked like at 350 miles. - Here is what they looked like at 1750 miles. Overall results and observations. I was pleased with the lack of sling. I like the black color, but not a fan of the greasy shine on tires. This product does not give the greasy shine. It is a light shine with a good black color to the tires.
