So...? Does Dr. ColorChip work?

[BigDToronto]

I just ordered Titan Silver metallic for my newly aquired E39 530. Anything I should watch out for? Follow the instructions...or is there a better way? I have a few road boogers on the front hood and a couple of minor sufrace scratches. The car only had 92,000 km when I picked it up so it is in like new(ish) condition. (Goes in to the shop for trans and diff oil changes this week coming)
