It took 41 years to match quote #2 from a famous Trans Am Racer.
"You know your car is fast enough when you can spin the white letters right off the car. "

That look really requires maintenace and careful application of any tire dressing. Any oily tire dressing that will sling makes matters worse. I re-did the letters on some vintage race tires and had good luck with the duplicolor yellow pen product.
Got this tip from a Vintage Club Racer:
I washed the tires with Bleech white to get the deep tire dressing out. Careful around the wheels though, keep em wet. Don't do this in the sun or get it on the paint. You will see the bleech white pulling a brown film off the tire. They say that is the embeded tire dressing. The tire feels kind of dry after , compared to acetone or laq thinner. The first coat goes on more even compared to my attempts using laq thinner.
Then I did the pain staking job of lettering them. I let them dry for a couple days and even mounted them with no issues. Then used the Meguiars tire gel stuff. It will dry after a few hours. So far it has held up, but only about 100 track miles and one wash. Bought some white to try on the GT, but have not had time. I think it looks great. Stunts showed this look off a year ago and it still looks cool.
