And while I don't know how long it will last, the last time I detailed my roadster, I went a little overboard using Meguiars Step One Deep Crystal Paint Cleaner and "cleaned" right over the strip with my Porter Cable 7424 and an orange pad.
I figured "what the heck", and used the Step Two Polish and it cleaned up very, very well. I used Turtle Wax Ice polish (just on the tape strip) and it really looks 100% better than ever.

I guess it was just the cleaning/polishing action that did it.

I'm not going to touch it again this year, so if folks are interested, they can see it at the Tail of the Dragon this weekend.
