Over the decades of my own tire rotations and wheel cleaning/tire cleaning, I have used one staple of a healthy lifestyle. Good ole Vaseline. I put a dab on the top few threads of a lug bolt (in the case of the XF) and for decades, the studs. After running the lugs in to the end, I back em back out and take any excess off. Until about the late 80's, I never torqued lugnuts. Ever since using the Vaseline on the studs, I have never had rust or any type of corrosion. After acquiring the torque wrench around the 1990 timeframe, I have torqued the lugnuts and recently, the XF lug bolts. In the last @ 3 1/2 years with the XF, I again used the vasi and torqued the bolts. No rust, no problems. I believe the vasi does a combination of two things after application. Normal evaporation (if you could call it that) over a period of time, and accelerated evaporation (when the wheels/rotors heat up from use). I make dang sure there is not enough to contaminate the pads/rotors and its never been a concern or problem. The super clean non rusting easily removable and installed lugnuts and lately, lug bolts are the result.
