Bf Goodrich brown walls

Bob's Barracuda said
I bought Bf Goodrich Radial TA's to go on the Keystone Klassics on my 68 Barracuda (yeah no school like the old school) anyway no matter what I try I can't keep the letters white. I can GET them white with lacquer thinner but it seems to draw the oil out of the tires and within a couple days they are brown again. Any ideas?

I posted about this about a week ago. I bought it at O'Reilly's. Follow the instructions. When you spray it on, you can literally see the brown melting off the letters. The left side of the tire below is after one application. The original brownish letters are on the right.
