This is a true story : I drove my 911S down from Seattle to Portland (Years ago) to a PCA National meet. Thought I would do the Concourse, so wiped the bugs off the front of the car, and went to register, a gentlemen in my class, came up in a "Panic" and asked if I have a #5 toothbrush !!!! I looked in my detail kit, and handed him, the (One and only) toothbrush I had, "Good God Man, that's a #2, that will never work on the tire tread" So Mike something to look forward too
Cheers TommyRot.
