After reading feedback on
Ultima Tire & Trim Guard Plus not lasting on tires, I decided I'd better do my own testing again. Here's what I did:
1. Washed tires thoroughly with Dawn dishwashing detergent.
2. Dried tires and allowed them to further air dry for 45 minutes in the sun.
3. Applied 3 coats of T&TGP with 30 minutes dry time between coats.
4. Drove the car for 300 miles... Hard!
5. Washed tires with straight Dawn.
6. Dried tires and inspected.
My experience on the Pilot Sports was fantastic. The attached pictures are Before Wash, During Wash and After Wash.
I tried the same test on a passenger car tire and the results were not as good. While the tire was still very black, it lost most of the gloss.
I'm beginning to understand that the flexing in the sidewall of the tire is causing the gloss to fade. So... I am experimenting with a "Glossing Polymer" and will offer feedback when I have an update.
