I've been thinking about coatings for the insides of the cabinets, as I'm going to be using veneer on the MDF, and you have to do to one side what you do to the other. And of course it would be nice if the coating had a beneficial effect on the sound. I'm reading about silicate loaded paints, rust-inhibiting compounds, butyl sprays, etc.
Anyone have any ideas on readily available coatings?

According to the "old school", of which I'm a charter member, veneering a substrate puts stress on it from the seasonal movement of the wood veneer, small as it may be. Therefore, you use a cheaper veneer on the other side to balance. Technically, you should even "counterbalance" plastic laminate, although no one does any more.
Spray water on, or apply a moisture-rich adhesive like hide glue to veneer on one side and watch it curl. When you use hide glue to veneer, you apply it to both sides, then scrape the glue off the face side after it dries.
That's why I am seeking a sprayed or brushed on coating, as much for the counterbalance effect as for sealing and sound damping.
