IF you want them to sparkle-prepae to use a soft toothbrush on them. We have them on our cars and they are superior to stock lines IMO. The reason is that they do not swell or degrade like stock ones. Brands-Goodridge (very well liked by NASCAR too) and Russell. I have sets from both companies for different cars and they are very similar. You can pay more for the Neuspeed coated ones, but they work the same.
