Thanks guys, now I know that it is normal for the EOS. Did not want to take her to the VW dealer, they know very little about the roof. Just purchased a bottle of the lube and the parts department did not know what I was talking about until I gave them the part number that I found in this forum. May give her a taste of the lube this weekend.
The key to using the VW Lube is not to apply too much. I use one of those really cheap foam brushes that you can buy from the local hardware store. works really well. The little bottle should fully lube the car at least 4 times.
If you put too much on, it isn't going to hurt anything. You will get the excess running off the seals and onto the paint or windows. Don't panic though, krytox (the oil used to lube the seals) doesn't react with paint or glass. Actually, it is food-safe. So you don't even need to wear gloves when putting onto the seals.
Washing it off is really easy too! (thankfully)
Simply get some car wash concentrate (don't use dish soaps) and mix according to the instructions on the bottle. Car soaps are formulated to be gentle on the car paint and any sealant/waxes that you have in place. When you soap up the car, the oil will come off without any problem and then during the rinse you will be left with a streak-free surface.
If, after a regular wash like this, there is still something left on the surface, then it probably isn't the seal lube oil. You could probably wash it off with a tar/bug remover, but you will need to rewax after that because those chemicals will take off the wax (just like dish soaps will).
