Not sure where this belongs, but as it's about saving the finish of the paint short term on long trips temporarilty, I thought it would fit here best:
Came across this while searching for white painter's tape, triggered by SolidJake's road trip pics on E46f where he has used blue painters tape to cover the nose and mirror on the car from stones, bugs etc...

This might be even better (8 MIL and 14 MIL available), but I wonder how easy it is to remove...But then again if it's made for racers and bikes as a temp protection solution, it should be easy, right?

I might try it during the next long hwy trip for Gretchen...
