Kevin,
I just bought a set of 200 mile Billboard's that had the Plasti-Dip on them. As Allen said, they had yellowed from soaking in the rubber/
oil, no biggie. But with a slight roll of the thumb, I removed an entire letter. I then prepped one of the words "Eagle" on one tire and did it again with PD and same thing, rolled right off. Not sure Ranger is going to hold up much better, they are already cracking in the garage and I haven't even mounted them yet.
