Thanks, guys! Appreciate the advice.
@Johnnysmoke. That had to be a heck of an experience. Glad your boat made it through the mayhem intact. My rack was professionally installed. When I grab the towers and push on it, the car wiggles (Honda Fit), but not the rack. Seems solid.
@kfbrady, bare roof car. Will check the bolts - I did regularly oil the bar mounts to try to protect them from the salt and grunge and do go through a touchless car wash at least once a week in cold weather. Will do the oil and 303 whenever it warms up here (snowing again - so much for shoes).
I’m OCD about the cam straps and bow/stern rachet straps, always daisy chaining them as they come off and keeping them in a specific bag which is stored indoors next to my Hullavators. Not because I’m a neat freak, but because I don’t have to chase them down. There is some wear on the cam straps; don’t know how often they should be replaced.
