Not at all, the any type of lube will do
I treat my seals with gummipfledge
+1 ^^^^^^ that's the same stuff I use.
Better for a car used by a lady, as no oil,WD40 etc. to get out of clothes if they happen to touch the rubber. (two women in our house,that's why I use gummmyyyyy)
Edit. The window can also be adjusted,it's in the guides somewhere.
