Stainless tanks and sound deadening

[marty9876]

Any thoughts on applying sound deadening materials, e.g. automotive butyl or alike to stainless tanks to quiet them down? Dynamat or Killmat etc.

My specifics are, I have a stainless water tank under my V-Beth and when it’s about 70-85% full it sloshes around a bit. I’m a fresh water, seasonal boat if that helps. I know stainless needs to breath, oxygen exposure and all that and the thought of applying what amounts a to a giant thick sticker over the tank seems like a bad idea but… it has be wondering. I used his material in my home HVAC lines about my home theater and it did a wonder in deadening the think HVAC trunk lines.

Stainless doesn't need oxygen access if it's completely coated and sealed from moisture.

Does the tank have internal baffles? [it should]
