having done some research at the local mall parking lot, you are correct. those were just the caps. didn't realize the roof was predrilled for the rack at the factory. i'm going ahead and installing a factory rack. i only do skis and from what i've seen the factory rack seems sturdy enough to handle skis only.

my question is, as i mentioned there is a super-flimsy rack previous owner installed that i want to remove (i could pull it off with my bare hands). what is a good way to plug the holes that were drilled for that rack to protect from corrosion?
