Do as Doug describes. No need to saturate under the feet but cover the areas around the outside edges of the foot pattern including the holes, screw it down with a 3/4" screw and then caulk over the top of the screws to seal it all up. It will last forever.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?
