How do you protect your bike from scratches? Anyone here use protective tape to protect a new frame? To which areas do you apply the tape?  I have a new frame and I am worried that other bikes sharing bike racks will scratch my ride.
I use helicopter tape. You can find it on Amazon or from most any race car supply shop. It's a little pricey but well worth it. It's very sticky and thick enough to absorb impacts from rocks. I use it on the bottom side of my downtube, on the drive side chain stay, and anywhere a cable is close to the frame.
