I will share one thing that has worked real well while applying the paint (I used an opaque white pen). I removed the tire/wheel from the car to make it easier to access to all the letters around the tire. After 2 coats and allowing a short amount of time to dry, I used a small block with 180 grit sandpaper and used it to scuff the raised borders of the letters. I found this to define a real sharp edge with a minimum of effort. I have done this on a couple of different occasions and I too like the "aged appearance" VS the "bright white", the brittleness of the paint allows cracks to form from sidewall flex. I guess we need flexible paint.
I seriously wonder if regular automotive paint could be mixed and if the proper amount of "Flex Agent" would create a paint that could be used that wouldn't crack????
