Door Seal Anti Freeze Solutions...

[the Spaeth's]

Does anyone have any good tips/tricks for treating the door seals that will keep them from freezing shut. We have a 20V avant and when we take it up skiing
and get back to the car I can barely get the rear hatch seal to let go. I am afraid I am going to tear the seal. The obvious treatments like Son of a Gun
don't seem to work. I thought of maybe trying Vaseline but I don't want to damage the seals in any way. I would really like to hear any good things to try.

thanks
