I also found Silicone to be effective.
In my case I laminated utility plywood to a thin oak veneer plywood and used a toothed scrapper ( similar to that used for floor mastic ) to get the silicone distributed.
I don't have a tape accelerometer to test efficacy, but a simple tap test sounds much better on this sandwich vs the same thickness of ply or MDF.
The wood glue binding the individual plywood layers failed before the silicone layer

I also used a toothed scraper and agree though I don't have an accelerometer that the "tap tone" sounds much more damped compared to a single sheet of anything. The "tap tone" of undamped ply is amazingly live and why people end up doing costly "translam" projects ala Magico.
It has been close to a month, and it is sort of dry. Certainly less tacky. I will most likely begin machining on Wednesday and see what happens.
