Audi Wheel Bolts

My A4 (2003 3.0) has tire bolts that rust and are very difficult to remove. I typically need to use a breaker bar to loosen up the bolt and even then the breaker bar requires a lot of force. (Last time the bolt stripped clean even though the proper 17mm carbon steel hardened socket was used. That required the bolt to be drilled out)

I live in upstate New York and we got a lot of snow so they use a lot of salt on the roads. The design of the hub where the bolts screw into have open backings, therefore water can just seep around the bolts. ie, The hole where the bolt screws into has no end, its just an open hole) I have worked on other cars that have lug nuts and with those setups, water can not leak through the back and cause rust.

I am curious as to what other audi drivers use to stop the bolts from rusting, a little bit of anti seize? Periodically taking off each bolt?

Thanks
