I was surprised to see how much thick white wax was used all over our 08 German built Rabbit.

Indoors? I parked my Mercedes for years in my garage from December to April and never had a spec of rust.

Were you living in Ontario? LOL!

My state uses a lot of salt in the winter and I live 1/2 a mile from salt water. After Irene this weekend my truck was covered in this white residue...which was salt, wind blown salt!

Park the thing when the snow flies, put some Stabil in the fuel, change the oil, pump up the tires to like 50psi, throw a cover over it, plug it in with a battery tender, and see you later, its good to spring.


My last Mercedes took a salt water bath about oh 4 years ago. I was coming back from the yacht club late one night and the tide was rather high, and I didn't realize this until the last minute...I ran through about 8in of water at 30mph, car was covered in the morning. Hosed it off and none the worse for wear after.

Thank you for your vote of confidence, but I think I'm going to get it sprayed before it sits anyway. I'll feel better knowing it has been. No holes however.

I get both my e46 bmw's krowned each year, no rust, a few drilled holes will not matter, it is better to get the spray in the panels. The plastic under trays are rarely removed, they can spray in between the body and the plastic tray, love those Canadian winters!

Yeah, their wands are pretty thin and flexible, the tips atomize nearly 360, and the plastic panels arent hermetically sealed - there are entry gaps and points.

What I've used on surface rust in the past is the white lithium/krown mix that my buddy gave me a tub of. It seems to work incredibly well.


Rust is rust and the issue with a grease mix is that the grease can have some moisture in/under it and keep a microclimate there. You want it to breathe and self-heal as a coating.

To fix properly, you need to cut it out, put new properly rustproofed (galvanized? but then be careful welding/heating it), and then have it properly rustproofed/coated on the inside and outside (be careful of crevices), and then properly primed, painted/blended, clearcoated, etc.

Not a cheap job to do it right but worth it... Good luck!



I don't think so. grease on metal doesn't trap water. not sure why you think that.

True. I remember my wife's 2000 New Beetle would drip that waxy stuff six years later, during the heat of summer. Must work, because when we sold it and my mechanic saftied it, he said "are you sure you want to sell this?" because he was amazed at what good shape it was in.

Not a BMW, but when I had my Lexus in last week for Krown, I removed all the plastic panels underneath, and also the rear under mounted spare tire so I could be sure everywhere was sprayed.
