I guess this is not Prius v specific, but Iwonder if I can get some advise. My v is one month old, and as I changed from v8 SUV, I have been very careful with the clearlance at the bottom. The other day, I noticed a small yet deep scratch below the door - at the lowest part of the side. It is about an inch in length but it is deep - deep enough to show the black coat underneith. It is almost like it was done by a sharp blade. I am not interested in having it painted as it is such a small scratch, but I do not want the scratch to get worse to be volunable to rust and paint chip. Any suggestion to prevent it from getting worse? I checked the forums, but many are from pre-2010. I wonder if some new technologies have emerged? Thanks!!
