Replying to Will my skis get damaged on my roof driving across country?

hey im driving from buffalo to tahoe next week and i will be carrying 4 pairs of skis two cambered and two rockered on my roof. they will be in the yakima fat cat 6 rack. my question is should i wrap the tips and tails up in seran wrap to avoid travel damage. salt and stuff. also is there any possibility that if they are in the ski rack for a long time will it mess with the rocker on my arg's and my hellbents. the ski rack tends to squeeze down on the rocker tip and tail and it makes it hard to close the rack making me think they will bend out the tip and tail. any suggestions?
