I appreciate everyone's warnings. I, at first, was in disbelief about WD-40 being bad for studs. But then, after more careful consideration, I realized I was basing all my car experience on living in Alaska for 25 years. There the salt and cold and moisture (snow!) is very hard on wheels. I always kept a second set of rims with snow/studs for winter driving (this is BD-- before DMC :) and so was taking rims off twice a year. I found had to have WD40 to get lugs off and then on again, and never lost a wheel. But, I live in a TOTALLY different clime now, so I will heed the advice of you sage DML'ers. No WD40 for my lugs. Now, please kill this thread.
