I worked over my redlines with the Bleche White and they look great. It took two attempts--apply, scrub, rinse, dry, repeat. During both rinses alot of brown crap could be seen in the water coming off the tires--road grime or some chemical in the tire? Anyway, I'm going to repeat the process one more time before the car show this weekend just to get them looking their best. Oh, and yes, the redlines really do stand out now, especially in sunlight.
Thanks for the tip Erik!
