I've used those wax pens on white lettering before. it works pretty good, but, it has one draw back. Ya know when you swirl 2 colors together they make a new color (red paint mixed with blue paint makes purple paint).?. yeah, that wax pen does that. Once it starts to touch the black wall, gets dirty, it becomes dirty white to gray.
Before you go painting the letters, take a rag and spray some Clorox Cleanup on it and rub the affected area. Maybe it'll come back with enough white to be acceptable. If it doesn't, then go ahead and paint, magic marker, or whatever it needs.
Sorry, but I like to wash and wax sometimes. Always wetshine the tires too. Now I have to add the white letter detailing to the task.
I found this on amazon for $4.70 free ship.
I bought something like that from O'Reillys. My wife scuffed up the lettering on one of the tires on a curb back in July. I removed the wheel, placed it on the kitchen counter (her idea) with an old towel underneath and told her to make it pretty again.
She did a pretty good job and the paint has held up nicely for over 3 months now.
Yes. It is a small strip of white rubber molded into the tire. If scrubbing doesn't get the sand paper should. I keep a small sanding block with a sheet of wet/dry sandpaper on it right next to my cleaning stuff. I just hit the white letters real quick when washing. Bleach or paint would only be used when the rubber is stained pretty deep.
