Vaseline or a good quality silicone grease is an excellent way to "connect the two surfaces". The grease forms an excellent vacuum seal between the two surfaces.
The effective atmospheric pressure (at sea level) is equivalent to about 14.7lbs/sq-inch; thus the effective pressure holding the two surfaces together is about 1,665lbs weight!! Properly applied the grease will not tend to migrate anywhere. It also takes up any deviation in flatness between the two surfaces.
I have use it with excellent results on my TT weights copper mat and alluminium Platter.
The problem is that it is damn difficult to remove the mat after a few months because of the amount of suction, as the two surfaces progressively bed down!!!!
