The key decision is what to do about Lake Constance, which is a bit in the way, and the short route involves passing through Austria. A lovely friendly people, with the worst attitude to visiting drivers I've ever ecountered. So my route was Lausanne > Zurich > Bregenz > Munich.

I drive down to St Moritz quite a bit. I *think* the E62 is the San Bernadino pass, which is quite heavily used by trucks. You're much better turning off to the Julierpass, at Thusis, just south of Chur. It's actually worth downloading Google Earth and setting up a route that goes Chur > Thusis > Tinizong > Bivio > Silvaplana, and letting Google Earth "fly" you along it. I last drove it in the Merc E500 about five weeks ago - but only going north, not south. When I arrived to climb up the pass, it was closed by snowfall, and I had to go to Davos to take the Vereina train tunnel. The whole area is really, fantastically good in any decent vehicle.

Which is odd because it does not have any fish oil in it!

The white lithium grease is far superior and will stay in place much better. I do all my door and trunk locks once a year. The spray is really key. Lets you apply it exactly where you want it.

So if you don't have anything but WD-40 go ahead and use it. It is certainly better than nothing.
