Don't know if it's due to the humidity in my area but the rubber seal/gasket that prevents water from getting into the trunk is preventing my trunk from opening easily.

If i pop the trunk, it'll unlatch, but i have to literally pry the trunk open because the rubber lining on the body of the car is stuck to the underside of the trunk.

I'm thinking of putting some petroluem jelly on the lining but not sure if it'll harm the lining itself. Any ideas?

Thanks.
