For budging rusty fasteners Kroil is better than WD-40 by far.
(but use what you have)

A proper socket and long breaker bar for the lugnuts (and the lugnuts after the chrome cap falls off) goes into all the cars.
Busting the cheap OEM lugwrench is to be expected for a stuck nut.

I use anti-seize on the lug threads occasionally. NOT the coned faces of the nuts and wheel but the threads. (My lawyer is aghast that I posted this in public. So don't do it. I died from it a couple of times last year. Probably will die from it a few times this year as well.)
