I just did my annual spring "return of the basket". I take the basket off each winter to avoid snow collecting, melting, refreezing and scratching the roof. Each fall when I take it off and each spring when it goes back on again, I also lube all 4 basket and all 4 deflector screws with a dab of vasoline. As per the advice given on this forum, I've also added rubber washers to keep any water from getting in to the threads. After 1 1/2 years (including 2 winters) all threads are still bright and shiney with no sign of rust!
